June bird walk

In June we birded at Blue Heron Lake and Strawberry Hill in GGP. I made a checklist from what I could recall. Might be missing a couple. I kept it running for another half loop of the lake after most of the group disbanded so there are a couple others added in like the brown creeper and red-winged blackbird.

Special shoutout to Taylor who made a most wanted checklist and a larger list of possible birds to look out for
most wanted checklist
the most wanted checklist from Taylor. We saw the Nuttal's and Wilson’s Warbler (briefly). Post walk a couple of us walked past a brown creeper too.
I took some photos:
red-tailed hawk
red-tailed hawk (Buteo jamaicensis)
american robin
juvenile american robin (Turdus migratorius)
another juvie
nuttal's woodpecker (Dryobates nuttallii)
probably a great blue heron nest
chestnut-backed chickadee (Poecile rufescens)
lesser goldfinch (Spinus psaltria) feeding!

The goal was to look for breeding behaviors so it was pretty neat to see the goldfinch and hairy woodpecker adults feeding the fledgelings and also the juvenile robins. Thank you to everyone who came out!




Summer Break

July is looking fully packed so we're going to take a one month summer break before picking back up again in August. Remember to bring those binoculars on your summer vacations:)




Spotlight Bird: Lesser Goldfinch (Spinus psaltria)

Seeing the lesser goldfinch family feeding was a highlight of our walk so I thought they'd be a good choice as our bird of the month.

Fun Lesser Goldfinch Facts:

  • If you look up pictures of them online you'll see some with an all black back, but the ones we see here on the west coast have the green back. These are sometimes considered the subspecies Spinus psaltria hesperophilus, or greeen-backed lesser goldfinches, but subspecies classifications are often debated.
    The paper titled Geographic variation in color, measurements, and molt of the Lesser Goldfinch in North America does not support subspecific designation argues that these variations are color morphs rather than actual distinct subspecies. I recommend going down the rabbit hole by reading the wiki on Phenotype plasticity
  • They are in the same genus as the american goldfinch and pine siskin. They are in the same family as the house finch.
  • They are found in sf year round.

  • Outside of SF they are seeing range expansion in the pacific northwest. Check out this paper for more.
  • Our word of the month is geophagia, which is when you eat the earth. Apparently lesser goldfinches have been observed eating soil.
  • Besides soil... they mainly eat seeds. In the pictures from our walk you see them on what I think is a thistle plant which is one of their favorite seed-producing plants to feast on.


Member Submissions

Thank you to everyone who sent me photos of the birds they saw!



To lead off Gus and Anjali up in Seattle did a lil birding

dark-eyed junco
dark-eyed junco (Junco hyemalis) singing his lil heart out. They've been very vocal here in sf too
eagle and crows
A baldie (Haliaeetus leucocephalus) being harassed by a murder of crows. Apparently you only need three crows to make a murder.



Next up Janet caught a junco working on its nest here in the city. If you recall last month we saw two submissions of the junco nests. Very impressive builders
