Tuesday, January 14, was the bimonthly bird survey at Ellis Creek for the Petaluma Wetlands Alliance (PWA). Shortly after 7 AM, the team was greeted by this incredible pink sunrise reflecting in the ponds.
Even in the near-dark, a large group of noisy Green-winged Teals gave their whistle calls in the first ephemeral pond. Don’t the whistles sound like reed instruments?
As the sun emerged, we came upon this male Anna’s Hummingbird in the coyote brush, perhaps prepping to perform some displays.
There must’ve been a Black-crowned Night-Heron convention going on at Ellis Creek – the team tallied a record high 39!
We listened to this Song Sparrow and delighted in his performance of four totally different songs in a row. Was it a first-year bird practicing his repertoire?
While we’re on the subject of sparrows, we finally recorded the Lincoln’s Sparrow’s high-pitched buzzy call note – listen to it below. This buzzy call contrasts with the more pure-sounding “zeet“-s of many of our other sparrows, and is a great clue that the dainty and dapper Lincoln’s Sparrow is concealed nearby. Here’s a refresher on how to tell the Lincoln’s apart from the Song Sparrow.
In one of the ponds, we encountered some solo diving ducks.
The team split into two groups to cover different sections, and ours headed down a side trail to scope the distant tidal marsh.
We met a couple Turkey Vultures at the bend, and they took to flight – none too happy that we walked by. Sorry, friends!
The exciting sight of 40+ Canvasbacks awaited us when we rejoined the other half of the group.
We all watched with great interest as this Red-shouldered Hawk alighted to a perch with lunch in tow. As for the unfortunate victim, its foot had long toes and looked rail-esque – our best guess was an American Coot! Click the photo below for a closer view.
In the world of bird calls, sometimes a bird’s alarm call is identical to its relaxed contact call, just given with more emphasis. It’s fun to notice this in the wild.
Listen below to a flock of Bushtits – you can hear their typical “tsit” calls (the dominant sound in the first 6 seconds – they sound like tiny tambourines to us) and the normal, high-pitched “tee-tee-tee” calls at 0:06 and 0:08 seconds. But, listen at 0:09 seconds as a Northern Harrier flies by. The calls ramp up greatly in intensity – the urgency is palpable!
Who’s got the biggest butt in the pond? Why, the Mute Swan, of course!
As we rounded back to the parking lot, this Greater Yellowlegs ran around foraging frenetically.
All those noisy Green-winged Teals from the morning had tucked away to rest.
By the end of the morning, the team had tallied 80 species. In the following days, three additional species were located by team members returning to Ellis Creek, bringing the grand total to 83 for PWA’s January 2020 survey.
If you have any questions about this particular count or if you’re interested in participating in future counts, please contact the coordinator/compiler for these surveys, Len Nelson, at lennelsn@comcast.net.
Very nice synopsis as always! It was indeed a perfect day for the survey!
Thanks, Deb! Always so good to see you 🙂
Lucky guys. Here at -15°C at noon, I was dreaming of spring wheather.
