How
many birds are still out there when it’s too hot to be out there?
I
decided to give it a test. I drove to a county outside of my normal
range. Frio County, south and west of San Antonio. The biggest city
in Frio County is Pearsall, population less than 10,000. There are a few
other towns in Frio County, but not many. Most of them don’t have
stoplights.
Not
much in the way of birding hotspots. I looked on google earth ahead of
time and picked out a few places that looked like they might have birds
though. I got to a spot outside Pearsall before dawn, parked at the side
of a dirt backroad for the morning chorus, and started counting the birds I
could hear. I picked a place with no houses around so I wouldn’t bother
anyone when I played a few bird calls out loud to encourage any silent birds,
birds that are normally only active at night, to say something. The great
horned owl call worked. Two of them answered. I heard a
pauraque. It was hard to hear anything else for the cardinals and mocking
birds, but I managed to pick out a few. A whistling duck flew over.
Moving
quickly, I drove back into Pearsall to a cemetery in the morning light.
That time from before dawn to about 9am is most precious. It’s the
morning chorus, the time that birds tend to be their most vocal and active.
Found some doves. Purple martins and a chimney swift. Moved to a
city park. Scissor-tailed flycatchers and western kingbirds. Moved
on to the fishing pond. More birds. Common ground doves and a
yellow-billed cuckoo.
After
nine or so the birding slows down, and the weather warms up, so I spent more
time in the car and toured the entire county to make sure I covered all the
different kinds of habitat available, getting out to walk around and check out
each promising spot. It turns out the habitat doesn’t change much in Frio
County. Scrubby brushy ranchland. It’s the parks and cemeteries in
the little towns that have the big trees and bushes that are attractive to a
lot of birds.
I
proved it was pretty hot out for birds. It was pretty hot out for
me. It was 114 degrees at 4pm when I called off the count for the
day. Hadn’t seen a new bird in the last couple hours. By scouring
Frio County from dawn to hot afternoon, I totaled 52 species. Yup, it’s
too hot to be out there, but the birds still are. I had left the air
conditioning set on 80 degrees in the house. It felt cold inside when I
got home, so I turned it up.
