We had some nice weather and decent banding activity at Chico this morning:
33 newly-banded birds and 3 recaptures of 14 total species.
Nothing too unusual species-wise, with Lincoln's Sparrows being the
most-caught species of the day. We also had a Hermit Thrush that, based on
its coloration and relatively small measurements, likely belongs to the
"Pacific Lowlands" subspecies group that is not encountered very often out
here.
One of the recaptured birds was a Willow/Alder ("Traill's") Flycatcher that
was banded last Thursday and then recaptured on Friday. This individual
weighed 11.9 grams and 12.6 grams in those first two encounters,
respectively, and today it weighed in at 13.6 grams. A great example of a
migrant loading up on fuel supplies at a stopover site to prepare for its
next long-distance flight!

Clay-colored Sparrow 1

We are open 6 days a week, closed on Sundays. This week we're opening nets
at 6:50 AM and closing at 11:50 AM, weather permitting. There will be a
large school group visiting again tomorrow, so the best time to stop by to
see birds without too much commotion will be between 7:00-8:30 AM. Come
visit!
