Site Description: I went birding in my backyard in Sacramento, California. There are various trees and shrubs in my backyard. Some trees are pretty tall while others are medium sized and the branches came down to just above eye level so some birds could be seen. I heard lots of chirping and bird sounds, but I found it hard to get a visual on all of the birds — just because the trees branches were so dense and it was hard to find the source of the sound. I walked around the backyard and also was looking around the trees in my neighbor’s yards. My neighbor has a very open grassy area in his yard and I saw a few swallows flying around over the grass. They also landed in a tree in my yard, after which I was able to identify it as a tree swallow. The area overall is flat and quiet overall. I did not see any birds on the ground level or in the lower bushes. Most were in the tree branches or they quickly flew overhead. I saw around 5 taxa and the key bird species seen included: American Crow, Oak Titmouse, Tree Swallow, swallow sp., Black Phoebe, and Yellow-Rumped Warbler.

Species Account: Oak Titmouse was a key new species I saw while I was birding. These birds were seen in the small trees. They were very quick but when they stopped they were noted to have a gray head and a white underbody. Its feathers on its head were shaped like a mohawk on its head. It made a high pitch chirping sound that was very distinctive, and matched the one on the Sibley guide. According to the Sibley Guide, these birds are an overall drab gray color on the head and wings with a white underside. They are known to be found in oak trees, although they also live in areas of open pine or other species of trees (All About Birds). Oak Titmouse belong to the order Passeriformes and the family Paridae (Wikipedia). Oak Titmouse flit between branches and fly with shallow undulating flight (All About Birds). Their diet mainly includes insects, nuts, and seeds (Audubon). Oak Titmouse choose their mates for life (Audubon). Females lay 6-7 eggs in each brood  and the young leave the nest about 16-24 days after hatching (Audubon).  

Narrative:

I went birding for about an hour in my backyard. I started birding around 3 pm and the weather was very nice. The sun was out and there was no wind or overcast. It was a very clear day. I mainly was looking in the branches for any movement and that is where I saw the majority of the birds. There was a couple times when I saw something move but it turned out to be squirrel. I did not see many soaring birds. I only saw a couple of swallows flying overhead/close to the ground very quickly. The birds that I saw in my neighbor’s yard that flew close to the ground very quickly I identified as swallows based on their flight, but I was unsure of their exact species because they were so quick. But I did identify a couple tree swallows when they landed in the tree. I also spotted a couple birds on the fence in the yard. Usually the birds would only sit on the fence for a few seconds before flying away. The Mourning Doves were one of the first ones I noticed. They were pretty big compared to the other birds (other than the crow I saw). The Mourning Dove had speckled spotting on its wing area. The Yellow-Rumped Warbler was a unique find for me because I did not see it at first because it was so blended in the branches. But I saw the bright yellow coloration stand out near its neck, and the black and white striations on its back. The Oak Titmouse was seen with a few others. They had a distinctive mohawk of feathers on their head, which helped me identify them. The Sibley App also allowed me to confirm the ID using the recordings. I saw one Black Pheobe when it landed on the fence. I was able to identify it by its gradient going to black to gray from head to tail. I was happy to see a familiar bird in Sacramento that we first saw in SF. Overall, I was happy with this trip because although I did not see a large number of birds. I did not think that I would see many birds during this time in my own backyard but I was surprised to see some of the ones I did!

Locations: 309 Smith Ranch Rd, San Rafael US-CA (38.0257,-122.5176) (5 m)

Site Description: We visited the Sanitary District area in San Rafael and made one main stop. We walked along the trails surrounding the site. It was mainly a marshland with a couple of pond-like bodies of water (see photo). The trails ran alongside the water and looped around back to the parking area where we began walking. There were smaller islands within the larger pond areas that had many of birds within the shrubbery there. One of the main birds we saw on these islands were the Black-crowned Night-Herons. These birds were perched up sitting in the branches. There were many unique species of birds that we had not seen before. There were several other people seen recreationally walking along the trail — some with other people and some just walking their dog. It was a very quiet and overall flat area. There were some trees along the trails, but they were not very tall. Along the shoreline, there was mainly bushes and shrubs along with some short trees. We saw Marsh Wren coming in and out of these bushes that were along the shore. These shrubs and trees were mainly at our eye-line. There was also a palm tree along one of the trails. There were not many steeps inclines along these trails. There were not many different elevations and but we were able to see a large variety of species on this trip due to diversity of waterbirds. Birds were seen at all levels— from the ground to the sky. We also learned some new bird sounds with Professor Paul’s help. Many birds sounds were heard and properly identification of the call helped us identify the bird — mainly for the Marsh Wren because it was hard to see this bird as it was so fast. There were around 40 taxa observed and the key bird species seen included: Canada Goose, Mute Swan, Blue-winged Teal, Cinnamon Teal, Northern Shoveler, Mallard, Green-winged Teal (American), Bufflehead, Common Merganser, Pied-billed Grebe, Mourning Dove, Common Gallinule, American Coot, Killdeer, Short-billed Dowitcher, Wilson’s Snipe, Greater Yellowlegs, Forster’s Tern, Double-crested Cormorant, American White Pelican, Great Blue Heron, Great Egret, Snowy Egret, Black-crowned Night-Heron, Turkey Vulture, White-tailed Kite, Northern Harrier, Downy Woodpecker, Black Phoebe, American Crow, Common Raven, Tree Swallow, swallow sp., Marsh Wren, European Starling, House Finch, White-crowned Sparrow, Golden-crowned Sparrow, Red-winged Blackbird, and Brewer’s Blackbird.

Species Account: Marsh Wren were a key new species seen on this field trip. These birds were seen in the small trees/bushes that were along the shore. The Marsh Wren were very quick and hard to spot — as they would flit from branch to branch very fast and disappear into the bushes. The birds were hard to get a visual on because they were so fast. But overall, they looked brown and had a distinctive call that was pointed out by Professor Paul. According to the Sibley Guide, these birds are a rufous-brown color on their wings and tail and prominent white coloration on their eyebrow area. They are known to be found in tall reeds of wet marshes, which is exactly where we saw them along the shore in a heavily wooded (that looked almost like tall hay coming out of the ground). They made a distinctive call that sounded somewhat like a repetitive rolling squeak/rattle like noise. It also fluctuated in pitch —  almost like an up and down from high pitch to low pitch very rapidly. Marsh Wren belong to the order Passeriformes and the family Troglodytidae (Wikipedia). Marsh Wren are described as overall small and round-bodied birds (All About Birds). Marsh Wren quickly flap their wings and make short flights within the marsh– flitting from branch to branch– and they grab onto the stalk of the branch (All About Birds). Songs are known to differ among Marsh Wren found in the East and those found in the West — with the Western birds having more songs and tend to be more complex (Audubon). Their diet mainly includes insects (Audubon). Females tend to lay 4-5 eggs in each brood (two each year) and the young leave the nest about 12-16 days after hatching (Audubon).  

Narrative: The class drove to San Rafael for this field trip. We left around 8 am on Thursday morning. It was a nice day overall with some overcast. The sun was not out much, but there were some times when the clouds would clear up and the sun would be out. It was not too cold and but there was a slight breeze. There was no fog coverage so it was a clear day to go birding and see birds nearby. We could also see the soaring birds well — like hawks and Turkey Vultures. We walked the area along the sanitary district near the water. There were lots of birds as soon as we arrived— mainly shorebirds and birds from Charadriiformes. We started at the parking area and wrapped around the first pond. We saw lots of blackbirds in the trees/along powerlines as soon as we arrived (see photo) We then continues and walked into the first and second pond areas and then continues to walk along the side of the second pond. We then turned around and made a full loop before returning to the parking lot. Small birds like sparrows and wrens were seen in the lower shrubs. Other birds like hawks, vultures, and crows could be seen higher in the sky or in taller trees. Apart from birds, we saw some river otters in the water. There were a few swimming around — we could only see them bobbing up and down in the water. We got to see a couple new and unique species to see that we had not seen before. For example, we got to see Marsh Wrens for the first time and hear their unique call. We observed how fast they flew in and out of the bushes. It was hard to see them because they were so fast. There were many birds in the air and we got the chance to see a couple new kinds of birds on this trip including: White-tailed Kite, Northern Harrier and a couple new sparrow species. The flat marshland also allowed for us to get visuals on hawks that were flying in the air. We were able to see a couple White-tailed Kites in the air. We saw one circling and looking for its prey. We had the opportunity to see a couple of swans in the water as well. Ducks and geese were the most numerous birds seen on the trip. I enjoyed this field trip because we had the chance to see many new species and more of the species we have already seen. It was also very eye-opening because it shows how difficult it is to identify birds in the duck family because they look very similar.

Locations: Muir Beach, Redwood Creek Riparian Corridor US-CA (37.8615,-122.5753) (5 m)

Site Description: We visited the Muir Beach area and made one main stop. We followed a loop along a dirt trail that was neighboring the actual beach. We started in the parking lots and walked on a trail along the driveway into the lot. There were lots of shrubs along this trail that were at our eye-line. There were also small to tall sized trees that we could spot birds in. We entered another dirt path area that was along horse stables and more open grasslands. There were mainly shrubs and some trees along this part of the trail. Some areas were widely open— like near the stables— where we were able to see swallows flying around. Some areas had open areas or short shrubs, where we were able to see many kinds of sparrows. There were areas of muddy dirt with littles grass coverage — like near the stables. There were also some tall grass areas that we ventured off the trail for and walked into. It was a mixed forested area with  some tall coniferous trees and some widely open areas with a huge variety of birds present overall. There were not many steeps inclines along these trails. There were different elevations and different views that allowed us to see a large variety of species on this trip. Birds were seen at all levels— from the ground to the sky. Some of the birds were hard to track as the smaller birds would flit around from branch to branch and it was sometimes difficult to get a good look at it. Many birds sounds were also hard, which helped in the identification process as well. The area where we walked was near the beach but not too close so the sounds of cars and people were pretty quiet so it was overall nice and scenic. A total of 30 taxa were observed and the key bird species seen included: Clark’s Grebe, Anna’s Hummingbird, Western Gull, gull sp., Brandt’s Cormorant, Great Blue Heron, Turkey Vulture, Northern Harrier, Red-shouldered Hawk, Red-tailed Hawk, Downy Woodpecker, Peregrine Falcon, Black Phoebe, Steller’s Jay, California Scrub-Jay, American Crow, Common Raven, Chestnut-backed Chickadee, swallow sp., Wrentit, Ruby-crowned Kinglet, Pygmy Nuthatch, American Robin, House Finch, Fox Sparrow, White-crowned Sparrow, Song Sparrow, Lincoln’s Sparrow, California Towhee and Red-winged Blackbird.

Species Account: Red-Winged Blackbirds were a key new species seen on this field trip. These birds were one of the first species seen as soon as we arrived. They were seen resting on the fence along a trail. The birds were black colored overall with a distinctive bright red patch on their wing area. When they fly overhead, you can see the distinctive bright red patch in their wing area — a key identifying feature. Based on the Sibley Guide, these birds were most likely adult males. They made a distinctive call that sounded somewhat like a squeak toy. It also fluctuated in pitch —  almost like an up and down from high pitch to low pitch very rapidly. Red-Winged Blackbirds belong to the order Passeriformes and the family Icteridae (Wikipedia). Red-Winged Blackbirds are a medium-sized blackbird that are very common in North America year round (Sibley). Males are black with the red shoulder patch, while females are streaked brown (Sibley). They are known to nest in wet, fresh and saltwater marshes, or brushy habitats (All About Birds). They tend to breed in pairs and pairs usually nest in close proximities — they even flock with other starlings and blackbirds sometimes (All About Birds). Their diet includes seeds and invertebrates (Sibley). Males are known to sit in high areas and make their calls to females, while females tend to stay lower to do their hunting (All About Birds).

Narrative: The class drove to Muir Beach for this field trip. We left around 8 am on Thursday morning. It was a sunny and warm day in the Bay Area and it continued to warm up later in the day. There was still a slight breeze. There was no fog coverage so it was a nice clear day to go birding. Upon arriving, we were accompanied by Dr. Paul’s neighbor, who is also an avid birder. We hiked the area around the beach where we parked the car. There were lots of birds as soon as we arrived— like the Red-Winged Blackbird, Ravens, and Crows to name a few. We started at the parking lot and wrapped around the area following trails along horse stables and last visited the beach overlook. Small birds like chickadees and sparrows were seen in the lower shrubs. Other birds like hawks, ravens, and crows could be seen higher in the sky or in taller trees. Some spots had very tall coniferous trees, in which a Red Tailed Hawk was seen to land in. Apart from birds, we saw some horses, some butterflies and even lizard along the trails. We got to see a couple new and unique species to see that we had not seen before. For example, we got to see swallows for the first time and observed their quick and undulating flight in the air — as they quickly flew up and down in the open areas. There were many birds in the air and we got the chance to see multiple kinds of hawks/falcons on this trip including: Red-shouldered Hawk, Red-tailed Hawk and a Peregrine Falcon. The peregrine falcon was seen from a very far distance as it was soaring high in the sky, riding the thermals. It was seen at a higher elevation than a Red-Tailed Hawk that was also soaring at that moment in time. There were also many Turkey Vultures seen as usual. When we ended at the beach area, we had the chance to see a Clark’s Grebe in the water. It was diving down and emerging about 30 seconds later. I enjoyed this field trip because we had the chance to see many new species and more of the species we have already seen. It was also very engaging because the bird activity was so high in the area.

Site Description: We visited the Mount Tamalpais area and made one main stop, where we walked along the trails to different parts of the forested area. We started off near the outdoor amphitheater and made our way around the park area, which was at lots of different elevations and there were many trails. Some spots were widely open, where there were just grasslands and spots of acidic soil where we saw little plant growth. Other spots were widely covered coniferous trees. It was a forested area with a few birds present, but a couple new species for the class to see. Most of the birds were hard to see as they were not seen flying in the open air that often. Most were covered within all the shrubs and trees so we could hear more than we could see.The area was far from any main highways so it was overall very quiet and scenic. The key bird species that were seen included: Band-tailed Pigeons, Acorn Woodpeckers, Northern Flickers, (Red-shafted), California Scrub-Jays, Common Ravens, Chestnut-backed Chickadees, Ruby-crowned Kinglets, and Dark-eyed Juncos (Oregon).

Species Account: Acorn Woodpeckers were the key new species seen on this trip and the ones seen most often in the area. These birds were seen mostly in the tall trees and they were seen in large quantities during our time on the trip. They flew back and forth from trees and tended to land on the base of the very tree high up — hanging on sideways. The trees that they built their acorn holes in were explained to be “dead trees” by Professor Paul. Professor Paul also pointed out that they flock together in groups and even work together to store their food. They had a very distinctive call that sounded almost like a squeak toy. It was repetitive and came as a burst of 3-4 “squeaks” every time we heard it. These birds were also very distinction in their color pattern when they flew overhead — flashing the white areas under their wings. Acorn Woodpeckers are medium-sized woodpeckers that are known to live in oak and evergreen forests along the Southwest and West Coast at higher altitudes (All About Birds). Acorn Woodpeckers have the key identifying feature of a bright red cap on their head. They are mostly black with a creamy white face. When they fly over head, you can see black and white coloration on their wings as well (All About Birds). Acorn Woodpeckers tend to live in groups and forage together by storing acorns the acorns they collect in holes made in trees or other wooden structures. (Audubon). They are known to be omnivorous and eat acorns and insects (Audubon).

Narrative: The class drove to Mount Tamalpais for this field trip. We left around 8 am on Thursday morning. It was a sunnier than average day in San Francisco, but still had a slight breeze. It continued to warm up as we got to Marin so it was a nice clear day to see birds. We hiked around the area around the amphitheater where we originally parked but did not see a large quantity of birds overall. It was a rather quiet day. But we did get to see a couple new and unique species to see that we had not seen before. There were not a lot of birds in the air either. We did see a couple Flickers in the air for a few moment— as they were quick in the air. These flickers were yellow colored and had soaring flight. There were not many Turkey Vultures or other soaring birds. Additionally, there were not any bodies of water in the area where we hiked, but we did make a stop at a beautiful viewpoint on the way back where we could see the water and a large portion of the peninsula. There were also many varieties of trees seen on this trip as well— ranging from rough bark to very smooth barked trees. It was also interesting to see how the acorn woodpeckers made holes in the dead trees in the area. Professor Paul explained the significance of keeping dead trees in the forest as well, as it is important for the ecosystem. We also learned that Acorn Woodpeckers tend to forage and store acorns together. I enjoyed this field trip for the unique new Acorn Woodpeckers seen and being able to hear a couple new bird songs that I had not heard before—especially the Acorn Woodpecker.

Locations:

Stinson Beach, US-CA (37.9062,-122.6505) (1 m)

Site Description: We visited a few locations along the highway in an area around Stinson Beach. We took a first stop along the highway. This area was mainly flat and was a viewpoint with a good look of the Bolinas Lagoon Preserve. It was a marshy area with lots of waterfowl present. There were some shrubs/bushes and small trees along with muddy areas near the water. Most of the area along this point were widely open and not heavily shaded where we were standing. The other two stops we took were both a couple minutes down the road where we had another look of the same lagoon, but we were able to see some different birds. They were the same type of areas as the first stop. Most of the birds seen were pretty stationary in the water. There were also a couple flocks we saw while observing the birds. The area was right alongside a highway and a school, so there was some noise from cars and people. But it was overall pretty quiet and scenic. The key bird species that were seen included: Northern Shoveler, Eurasian Wigeon, American Wigeon, Mallard, Northern Pintail, Bufflehead, Anna’s Hummingbird, Killdeer, Long-billed Curlew, Marbled Godwit, Western Gull, Larus, Double-crested Cormorant, Great Blue Heron, Great Egret, Snowy Egret, Turkey Vulture, Osprey, Red-tailed Hawk, California Scrub-Jay, American Crow, Song Sparrow, and some unspecified duck and gull species.

Species Account: Long-billed Curlews were seen a few times on this field trip. Curlews are known to be found along much of the Pacific and Atlantic Coastlines along with the midwest area (eBird). Curlews tend to be is mottled brown overall, with cinnamon underwings– sometimes have striping on the head (Bird Web). Curlews are one of the largest shorebirds and they have a larger than average sized body. They are a long-legged shorebird with a long and thin curved bill with long neck and small head (All About Birds). Their habitat includes short grassed areas along with wetlands, mudflats, flooded fields, beaches, and sometimes prairie (Audubon). Curlews forage and mainly eat burrowing prey like earthworms, shrimp, crabs in the mud along the shore with sharp jerky pecking movements in both their bill movement and their walk (All About Birds).

Narrative: The class drove to Stinson Beach for this field trip. We left around 8 am on Thursday morning. It was slightly chilly in the morning with fog. It was cold near the Lagoon with some fog coverage, but the birds in the water could still be easily seen. There were a couple flocks seen in the sky during the trip and there were a lot of birds in the water and along the shoreline– both in the trees and bushes/shrubs. It was interesting to see how there were some species seen at all three stops and some birds were unique at the locations– despite them being so close. I enjoyed this field trip for the new types of water birds we saw in the lagoon, along with the new perspective of views.

Date: Thursday (January 30th, 2020)

Location: Golden Gate Park, San Francisco, CA.

Latitude and Longitude: (37.773860, -122.455811)

Elevation: about 92.0 m

Site Description: We mainly visited the northeast corner of Golden Gate Park. The area was at different elevations as there were various inclines and hills. The site had dirt trails and many trees along the sides of the trails, along with some shrub areas. Some areas were shaded by trees, while others were widely open and birds could be seen clearly soaring in the sky. It is a common tourist attraction and the noises of people and cars can be heard throughout the park. The key bird species that were seen included: Bushtit, Golden-crowned Sparrow, Dark-eyed Junco, Common Raven, Anna’s Hummingbird, Gull, Rock Pigeon (Feral Pigeon), Red-tailed Hawk, Black Pheobe, Steller’s Jay, California Scrub-Jay,  American Crow, Chestnut-backed Chickadee, Ruby-crowned Kinglet, and the rare find of a Red-naped Sapsucker.

Species Account: Dark-Eyed Junco was one of the main species that was commonly seen in the park during this trip. Juncos are one of the most common birds in North America. Junco adults typically have gray heads, necks, and breasts, gray or brown backs and wings, and a white belly. They can show a large amount of variation in their coloration. The white outer tail feathers flash distinctively while the bird is moving. The male adults tend to be darker than females. Juncos are small birds– typically the size of sparrows and larger than other birds like hummingbirds. Their habitat includes coniferous areas or mixed forest areas throughout North America. Juncos forage on the ground and mainly eat seeds and some insects (All About Birds). Juncos tend to be monogamous and defend their territory during the nesting/breeding season. Males do a bow, quiver their wings, fan their tail in display in the attempt to attract the female (Wild Bird Watching). Juncos build their nests in a depression in the ground that is hidden by vegetation or shrubs (All About Birds).

Narrative: The class walked to Golden Gate Park for this field trip. We left around 9 am on Thursday morning. It was a sunny day with little to no cloud coverage. It was warm weather and there were many birds visible in trees, shrubs, on the ground, and in the sky. There were a few other birders who were also out during the day and they were able to identify a rare find (Red-naped Sapsucker) for our class and also explained why it is a unique find in the area. This was a very informative field trip as it allowed me to get a better idea of how to use the binoculars to observe birds along with seeing the vast diversity of birds that can be present in such a little amount of land.
