Notes:
There have been no major weather fronts over the past week, and as a
result migration has been quite slow. There were 8 new species for
the year, but most of these were seen only in small numbers. A
Peregrine Falcon was viciously pursued across the site by a Merlin on
Wednesday morning, only our second sighting of the former species.
The slightly warmer weather on the weekend brought in Common Loon, Chimney
Swift, Cliff Swallow (these three species all fly-overs), Solitary
Sandpiper, Common Yellowthroat, Rose-breasted Grosbeak, and Bobolink.
We
had four days of banding this week, but three of them were at least partly
compromised by rain and/or wind. Nonetheless, we banded good numbers
of Red-winged Blackbird (21), Cedar Waxwing (15), and American Goldfinch
(16), and had our first captures of the year for Yellow-shafted Flicker,
Common Yellowthroat, and Common Grackle. We look forward to a bigger
influx of migrants with the next major push of warm air from the south.
Though common at MBO, we had
not banded a Yellow-shafted Flicker until this
third-year male landed in net A1 this Wednesday. (Photo by Marcel Gahbauer)
