Bird Question!
A sighting of a rare
Townsend's Warbler posted on
MDosprey on March 11 got me athinkin'. This bird was seen and identified (and beautifully photographed) one morning at a park in Montgomery Co., MD. After that first viewing, however, subsequent visits to the park could not relocate the bird.
I started thinking about how rare it was for this bird, normally of the west coast, to turn up in Maryland and how rarer still it is for someone to have found it. My question is, then, how many of these rare wanderers are not found? How many Townsend's wablers end up in the yard of a non-birder or someone on vacation instead of someone who watches their feeder? I would venture a guess that only about 10 percent of out-of-place birds are caught. What do you think?
