Morning all. I awoke this morning to the distinct call of a Broad-winged Hawk outside our bedroom window in one of the huge Pin-Oaks in the front yard. It was the typical 2-part high pitched whistle, but something sounded a tiny bit off. Not sure if it was the off pitch or slight "broken-ness" of the call, but it wasn't as fluid sounding as I felt it should. I've heard our Bluejays mimic Red-Shouldered Hawks and can almost certainly tell the difference between the real Hawk and Bluejay mimic. The Bluejay version is just not as cleanly done. (I'm an audio engineer, so sound is kind of my thing. lol) Would a Bluejay mimic a Broad-winged Hawk? I am not sure if they breed in CT so if they just passed through, I was wondering how the Jays would even spend enough time around them to learn their call. I am leaning with Bluejay though because they have been camping out in these trees with the absurd abundance of acorns this year. I've seen Broad-winged hawks fly over but never had one hang out on our property. Happy Birding. Brian Kulvete Bloomfield, CT

I'd suspect a mockingbird before a blue jay - I've heard/seen them do perfect hawk calls!

Could an immature bird not quite be up to standards yet?

I had a Broad-Winged Hawk nesting in the woods behind my house in Stamford about 10 years ago. Heard its squealing cry all summer. Never came back though.

Hi Brian -- to answer your question, yes, Blue Jays will certainly mimic Broad-winged Hawks. And it doesn't seem to be too unusual; I've watched them do it a few times myself. See Graves (2005) <https://repository.si.edu/bitstream/handle/10088/4520/Graves--Banisteria_vol_25_page_50_2005_Vocal_mimicry_of_b.pdf> .
