Steady March of Migrants

It’s a magic time for the dunes longshore tower.  We’ve entered that period where anything is possible.  From new arrivals to rarities, it’s the period birders get most excited about.  It will last until the end of May for most of us in the Great Lakes.  From Golden-crowned Sparrows to Ruffs, the possibilities are endless.  Unfortunately, for today, April 18, the rarities remained just a possibility.

While the flight was moderate and the birds were certainly migrating and diverse, no new arrivals were logged today.  It remained much of what we’ve seen already.  However, we did count 7,574 birds to add to the season’s total, including many female Red-winged Blackbirds.  The total of 65 species was down slightly from previous days.  Thus far 138 species have been logged for the year.

Most notable was the beginnings of the Blue Jay flight.  For those who have followed in the past know that the Blue Jay migration can be spectacular the first week of May. On some days 5,000+ bird will go by west to east. Thus far we’ve logged single birds here and there.  Today’s 71 was a noticeable uptick, though far from where it will go in the following week or two.

Raptors were generally weak today, which was a surprise given the perfect southeast winds.  87 birds of prey went by. Sharp-shinned Hawks led the pack and Broad-wings, kestrels, Osprey, and Red-shouldered were only singletons today.  It was the first hawkflight in a while with no Merlin.  One surprise was the late push of 60 Sandhill Cranes that moved through the dunes today.

For the week going ahead, we hope to get one last good count in tomorrow before wind and rain get dicey.  The forecast shows a good north wind flow for Fri-Sun, but a nice south set up coming for Monday and Tuesday of next week.  This next south wind will really start to bring in the warblers, orioles, and tanagers.  Things start to get exciting now!
