Totally! A *blue jay* or *blue jays* around Greenlee Wildlife Preserve, Boulder County, has been doing brilliant *Cooper hawk* imitations for the better part of a year now.
Not just an isolated *kek* or series thereof, but, rather, the entire repertoire: *kek... kek... KEK! kek...kek-kek-kek-kek-kek KEK! kek...* Gets me every time. I assume this is a relatively new thing with Denver metro region *Cooper hawks,* given that the species began its extraordinary continent-wide urbanization only in the past 40 years. I'd never noticed it myself until the past year or so. On another front, I can report that there was an extraordinary migration of *dainty sulphurs,* *Nathalis iole*, this past Sat., Oct. 9, at Rocky Mountain Arsenal National Wildlife Refuge, Adams County. The winds were brutal, but the clever butterflies were migrating just inches above the ground on a broad front southward--even though the prevailing winds were straight out of the west. Alejo Williams Viveros and I counted hundreds, and probably saw thousands. Good "migration" of *tumbleweeds,* *Kali tragus*, out there, too, haha. But they were headed east... Bird-wise, things were challenging. We had one (*n*=1) each of *pectoral sandpiper, long-billed dowitcher, Wilson snipe,* and *greater yellowlegs.* Decent numbers of *festive tiger beetles,* *Cicindela scutellaris*, in appropriate habitat, and a nice *showy grasshopper* (a. k. a. *handsome purple-striped grasshopper*), *Hesperotettix speciosus*.
