Back in late December, I posted photos of a Pretty strange bird that was frequenting our feeders. It is nesting on our front porch. It is pretty difficult to catch the bird visibly near the nest, let alone to photograph it. When Patches is on the nest, all that can be seen of her from the entry hall of the house (through the window above the front door) is the top of her head. Without climbing a ladder, even the nest cannot be seen from the porch.
BTW: I've just this morning learned [from an entry in KSBIRD-L Digest - 5 May 2015 to 6 May 2015 (#2015-126)]that the preferred way to describe such a bird is as "patchy leucistic". I'll be pleased to adopt the "patchy"; but, my spelling remains "leucastic" until there is wider agreement on the word's spelling.

this is my beloved white crow photo. the bird is sitting on the soccer goal at Gallaudet U., my former employer in NE DC. Most "white crows" look like this....not all of them are pure white.

As I wrote, above, "When Patches is on the nest, all that can be seen of her from the entry hall of the house (through the window above the front door) is the top of her head." At least I was able to get an acceptable photo, today!
