Re: [cobirds] Migrant Poorwill doesn't flush until I touch him

I was up at Centennial Cone Park 5 or 6 weeks ago and one of the volunteer park guides passed me and my on-leash dog while we were walking in. After telling him I was birding and specifically looking for Dusky Grouse, he said there were 2 dead "grouse" in the middle of the trail about a 1/4 mile farther. They turned out to be Common Poorwills. I'm wondering if their behavior didn't get them killed as this a heavily biked area. If they were day-roosting on the trail, fast moving fat tired mountain bikes might have squashed them before they could flush. One of them just looked flattened as if it was just perching on the ground and run over. The second was splayed out like it was hit while flushing with wings extended. Sad to see. Hoping others pick a better spot to day-roost next year.

Thank you for the suggestion. It was sunny and 60 degrees at the time, and there
was actually more than usual bird activity all around him from Flickers, a resident Towhee,
a Robin (first in a while), and others.  But perhaps the Poorwill was exhausted from his
journey and still recovering from nighttime torpor.

The bird was probably in torpor to save energy during the cold evening and morning period.

I've looked right at a Potoo without seeing him until he was pointed
out to me.  But today's Poorwill was a stunner.
At 10 this morning I was slowly advancing on a pair of canoe cushions
along the side of my tennis court, which is edged with river rock, to see if
I could spot any hard-to-see spurge weeds amid the rocks.
I wasn't making any noise, except for moving the back cushion ahead
and sliding onto it.  I noticed an odd-shaped bundle between the
chain-link fence and the rocks, but paid no attention to it. Even when I was
seated right alongside of it-- less than 12" away--I noticed nothing,
but spent some time picking up some debris on my other side.  Maybe I
shouldn't have been wearing my distance glasses!  Anyway, my curiosity
finally kicked in and I put my hand on it to pick it up.  It flushed exactly like
a Grouse (like an airplane taking off), startling the heck out of me.
Was it asleep until I touched it?  Possibly, but I think it more likely it was
awake by then and just was relying on its camouflage.
