High Pressure in Canada keeping us from getting new birds

Happy Memorial Day! I am so thankful for our freedom! Many Thanks to all the servicemen and women who keep this country and world free (as best we can)!

Another Northeaster today with the lake really churning! Numbers were decreased by half from the day before with 57 new banded birds and 25 recaptures. The speciation was good with 25 species banded with 12 of them being warblers. Warblers seen on site were: Blue-winged, Tennessee, Yellow, Chestnut-sided, Magnolia, Black-throated Green (nice looking male!), Blackburnian, Bay-breasted, Blackpoll, Black-and-white, American Redstart, Prothonotary, Ovenbird, Northern Waterthrush, Mourning, Common Yellowthroat, Wilson’s, and Canada.

The winds are not forecasted to turn around to the south until Tuesday night into Wednesday. Rain chances are on the increase as well. I expect the flycatchers and Red-eyed Vireos to be in larger numbers then. They have the urge to go north wherever they may be this time of year and may not stop to visit NW Ohio if the winds do not guide them here.

Top 5 species:
Magnolia Warbler – 7
Swainson’s Thrush – 5
Wilson’s Warbler – 4
Canada Warbler – 4
Red-winged Blackbird -4

Here is a mystery bird for you to figure out:

Take a look at this Magnolia Warbler and from the wing coverts you can see it is a second-year bird and a black face mask makes it a male. The wing coverts are worn and off-color with the alula (thumb feather) also worn and pointed. The coverts are the best aging tool to determining age for most warblers. It is important to understand the demographics of each species. It does the species no good if you have all adults in the population or all males. Banding is a tool to sample the populations to determine how well they are doing. Mystery bird is a female Common Yellowthroat. She is quite cryptic in coloration. The brightest color is however on her throat! Enjoy the day!
