While we are on the subject of accipiters (A question from yesterday on Sharp-shinned vs. Coopers'), at Lincoln Park, in West Seattle today, I heard / noted, my first Coopers' calls of the year, that I expect are territorial calls. As many of you may know Coopers' Hawks are usually silent, so hearing these calls are noteworthy. I suspect this Coopers' was setting up its nesting territory for the season.
Also at Lincoln Park - West Seattle today, I heard my first 2 parted call notes for the Purple Finches there, whose song heard FOY, on Sunday, 3-12. The 2 parted call note came with the treat of a close up look at a male, in low branches, when they are usually too high to get good looks without binos. If anyone has a transliteration of their 2-parted call, into the Roman alphabet, I'd be interested in what you call it.
In other bird notes, a Barred Owl gave its "Who Cooks for you" at about 5:20 pm today, a bit earlier than usual, and in full daylight, while about 4 mornings ago between 4 and 5 am, I heard what I expect is some kind of courtship vocalization of a longer series of hoots that are the same, followed by a longer "howl-hoot" as I just decided to call it. As far as I know, this last type of vocalization is not given year-round. (When I've led my owl walks, I've also referred to this series of roughly equal hoots, followed by that elongated "howl-hoot" as a "monkey holler", while I make a gesture that I grew up seeing monkeys in the cartoons doing.)
Also in Lincoln Park, where I spend much of my time in my recreation and therapy of weeding, in growing bird habitat news, I continued to make progress clearing a weed-free, mossy radius away from the colony of the, previously lost from Seattle, locally native thistle species I have reintroduced - Cirsium brevistylum - Short-styled Thistle, with countless seedlings from last year's mother plant's seeding. Fellow park birder Mark Ahlness and I were talking about looking forward to the day we catch some Goldfinch in the act of feeding among the seedheads in the growing colony!
