TN-Birders, Jeff Wilson noted that my description of the Rough-legged Hawk on Saturday in Cumberland County didn't fit the dark morph description. (See his recent note at the bottom). For anyone else struggling with the variation in Rough-legged Hawks, I thought I'd include the correspondence. I hope it's not too confusing to follow. I thought I'd checked the books carefully, but I agree that both Sibley and Wheeler & Clark say and show the upper side of the tail is dark on adult dark phase female Rough-legs. I had struggled over another dark-looking Rough-leg at the same place last year, though then I had a good look at it perched and saw that the upper 1/3 of the body (including head) was paler than the lower breast and belly. I very much appreciated Jeff's response then (his response to my sighting last year is in boldface below), and his follow-up this year. This year, I didn't get a good look at it perched (only a distant scope look with gray sky in the background). I suspect that this was the same individual as last year, and that it was a rather dark-appearing light morph female as Jeff reassured me then. From above, Saturday's bird looked like Sibley's light adult female (all dark with a very distinct white band), but from below it certainly looked dark, except for the silvery flight feathers. The white on the tail from below wasn't prominent. Ed LeGrand Crossville, Cumberland Co., TN Attached is Jeff's reply to me last year (including part of my description of last year's bird): A dark, heavily marked, intermediate light morph female Rough-legged could have all of the features you mention. I had one a couple of years ago on the Great River Road. Good Birding !!! Jeff R. Wilson / TLBA 6300 Memphis-Arlington Road Bartlett, TN 38135 http://www.pbase.com/ol_coot/ What is this feathered thing that lifts my heart to the heavens. In a message dated 3/3/2009 10:05:01 P.M.

In flight it looked most like Sibley's dark adult below, but it had much white on the upper tail with a solid black terminal band (similar to his light adult female but with more white on the tail--Sibley shows only dark upper tails on his dark phase illustrations). ----- Original Message ----- From: OLCOOT1@xxxxxxx To: elegrand@xxxxxxxxxxxxxxx Sent: Sunday, February 14, 2010 10:38 PM Subject: Re: [TN-Bird] Dark phase Rough-legged Hawk in Cumberland Co., Feb. 13 In a message dated 2/14/2010 12:24:51 P.M.

Do you have mention of such an upper tail pattern? All the dark morphs (few) I've seen have had dark or dark gray and black cross banded upper tail surfaces............How well defined was the black band? What % of the tail was white? Thanks for any input............
