Grosbeaks returned early this week, and within a couple of days
we had banded our first three males. This after-second-year
male was unusually
gentle, only once briefly nipping the bander; the second-year male
banded later the
same day applied a much firmer grip with its beak! (Photo by Marcel Gahbauer)

Finally this week it felt like spring has really arrived! With
temperatures up to 26 Celsius on Tuesday we expected the push of warm
southern air to bring in a fresh load of migrants, and Wednesday morning
we were not disappointed. All of a sudden there were Yellow Warblers
everywhere, along with smaller numbers of Baltimore Orioles, and various
other warblers and flycatchers. We recorded a single-day high of 56
species, despite being present for only 4 hours! A sudden reversal
of weather brought sub-zero wind chills the next morning, which put an
abrupt halt to the migration once again.
again cost us a couple of days, and so that banding total for the week
isn't great, though the hourly rate is much higher than we've had all
season. From the days that we were able to open, banding
highlights this week were many. We added 10 species to the list of
species banded this spring, of which 6 were altogether new for MBO:
Yellow-bellied Sapsucker, Great Crested Flycatcher, Least Flycatcher,
Yellow Warbler, Rose-breasted Grosbeak, and Baltimore Oriole. In
total, we also added 16 species to the list of species observed this
spring, bringing us to 100 with a good number yet to arrive.
we took a day of from regular operations to hold our all-day Birdathon.
Despite a cloudy, cool, and largely rainy day, we were able to find 108
species at MBO and beyond, and in the process raised over $1500 for McGill
Bird Observatory and Bird Studies Canada. Click

Another splash of red this
week came courtesy of this male Yellow-bellied Sapsucker.
Although the sapsuckers have been back in the area for a few weeks, they
generally remained on the far slope, and this is the first one ever banded
