After reviewing my notes describing this bird yesterday, and checking several references, I have determined that this bird is an immature bird, not an adult. With high-powered scope views, one could see very fine black streaks on the crown, and more concentrated in an arc around the hind crown. These didn't show in binocular views, or in flight. However, while the bird was perched and preening, they could be seen. Also, we determined that the primary projection was longer than the outer tail feathers on this bird. Comparing photos to the bird photographed in Rice County (MOU Gallery), that individual had much longer tail feathers than the wing projection.?
Quoting Bill Clark in his HAWKS field guide: "Immature:..... Forked tail is shorter than that of adult. Some individuals have fine black shaft streaks on head, nape, and breast feathers." Other characters described there didn't match, such as a greenish gloss to the black feathers. However, there is implied variation in the text.? This is still an immaculate, beautiful bird! We had such an amazing show. Several behaviors were observed. A favorite moment was when the bird was perched at one point and extended its wings, its chest pushed forward and head held high--- looking much like the Greek statue, "Winged Victory!" Beautiful!!! My previous experience has been only with birds flying or soaring by down in Florida. The opportunity to study one for prolonged periods was a wonderful treat! Hopefully it's still in the area for others to enjoy. Good luck to all searchers. Drew Smith Eagan, Dakota County -------------- next part -------------- An HTML attachment was scrubbed...
