a favorite long-distance migrant

Black-bellied Plover & American Golden-Plover - Wikim. Commons, D. Sherony


I had one of my favorite long-distance  migrants, (pictured at right in the photo), the American Golden-Plover, this morning on Hwy P north of Port Washington. Looking back in my records, I realized that I had not seen any individuals of this species in Ozaukee County in 28 years! And what an amazing species it is: the tremendous numbers we had before 1850 never fully recovered from the market-hunting days. Their long distance migration is staggering, with some birds traveling 8,000 miles +, one way. The Cornell "All About Birds" species account contains this fact: "Some adults arrive on the wintering grounds in southern South America before the last juveniles have left the Arctic."

my bird of the week - Winter Wren

Ph - Wikim. Commons - Ron Knight
In the forest on some of the Apostle Islands, this bird expresses the spirit of the place with its song:  http://www.xeno-canto.org/175234

Here's a great description of the Winter Wren's habitat, from the Bent life histories series: "To see it, or rather to hear its tinkling, rippling song, to best advantage, we must visit its summer haunts in the cool, shady northern forests, where the sunshine hardly penetrates, where rotting stumps and fallen tree trunks are thickly covered with soft mosses, where dampness pervades the atmosphere near babbling woodland brooks, and where a luxuriant growth of ferns springs from the accumulation of rich leaf mold to nearly hide the forest floor".

And it IS a spectacular song.

"to provide birds the best fighting chance of surviving threats, at least half of the boreal forest should be protected"

Worth reading, from the Boreal Songbird Initiative:

"To provide birds the best fighting chance of surviving the dual threats of habitat loss and climate change, at least half of the boreal forest should be protected from industrial development."
