[Tweeters] Study examines memory in expert birdwatchers

[rw]

I found the article in Proceedings of the National Academy of Sciences of
the United States of America, Vol. 119, Issue 26 (2022): article 2204172119.
This is in the (second?) Psychological and Cognitive Sciences section of
that issue.

Re Steven Wood question about sample size of the study:

Sample size: 66 experts (73% female) and 57 controls (75% female).  All were
in the Toronto area.  The experts, i.e., could identify more than 20 species
found in the local habitat and had bird knowledge beyond common backyard
species, had mean age 48.1 and a mean of 18.1 yrs education.  The control
persons were outdoor enthusiasts (gardeners, fishers, hikers, etc.) who had
no local bird knowledge beyond common backyard species, and they had 47.9
yrs mean age and 17.6 yrs mean education.

I had Pacific-slope Flycatcher nesting *on* my house (literally, on the bend
of a downspout, 6 ft off the ground) - in Lake Forest Park twice. I was able
to extensively photograph parents and later juveniles from both outside and
inside of the house. And, I hear them every year in season from tall
conifers around the house. 

Best,

Stan in LFP

"The memory test centered on bird pictures.



Wonder how large a sample they had?



Who can find the published study? I haven?t looked very hard but have
looked."


The study is linked at the bottom of the ScienceDaily article, but a direct

While a Merlin could probably catch a hummingbird, I wonder about the
calorie math.  A hummer can't be more than a few mouthfulls.  The Merlin may
not be willing to engage in the incredible gyrations it would take for that
small a reward.  As with anything in the bird world....it depends on how
hungry the bird is.

Be sure to visit the Balcones NWR not far from Austin. Broken hill country.
Go in the morning, because Austin will be hot this time of year!

I have birded several places around Austin over the years during family
visits. As Gary said, it will be hot for several weeks (currently over 100),
so get out very early in the morning wherever you go. My top two
recommendations are Hornsby Bend and Commons Ford Park, and they are the top
two species-wise in Travis County. Roy Guerrero Metro Park is also along the
river close in town, or just an early morning walk along the trail on the
south side of the river in town near the bats. Balcones Canyonlands is
great, but chances will be remote to find Golden-cheeked Warbler or
Black-capped Vireo in late summer. McKinney Falls SP just south of town is
another possibility. If you want to go north to Williamson County, you could
try Lake Creek Trail-West or Berry Springs. I suspect that Devine Lake and
Granger Lake would too hot in August.

I lived in Austin for 7 years.  I avoided birding places in or close to the
city because of the noise, tough to hear the birds.  You also have to deal
with lots of traffic.  But Phil?s suggestion of Hornsby Bend and Commons
Ford Park is a good one.  He?s spot on about the heat.  Wherever you go, get
there at dawn.

 

And if you have time, and are able to hike a bit, you might try Barton Creek
Wilderness Park where you might get lucky and see a Limpkin.  Limpkins have
exploded and an amazing range expansion is happening.  They are popping up
all over the central/eastern part of the country.  Here are a couple of
ebird reports of the Limpkin at Barton Creek WP dated today.

Best wishes for a happy and safe trip,

Hi Tweets,

I am heading to Austin, TX in a few weeks to see the Mexican Free-tailed bat
colony under the Congress Ave Bridge and want to do some birding during the
few days I?m there. If anyone has recommendations of good spots in that
area, I would love to hear them.

Happy Birding!

On the other hand, what about an orderve?  I once observed a Merlin fly in
casually from a long distance to land in the top of a gigantic oak tree on
Sauvie Island near Portland.  As it happened a Bushtit flock was foraging
there.  As the Merlin landed it casually reached out with a foot and nabbed
a Bushtit.  No chasing was involved and I wondered if the capture was
planned or just a last-minute target of opportunity when landing.

Dear Tweeters,
My bookshelves are sagging! I think it is time for me to unload some bird
magazines. I have a big stack of? old issues of?Birding that I would hate to
toss in the dumpster, so if anyone wants them, please let me know. I also
have quite a few years' worth of Sandgrouse that should go. This is the
quarterly publication of OSME, the Ornithological Society of the Middle East
, the Caucasus, and Central Asia).
Yours truly,
Gary Bletsch
