Field guides offer a range of northern breeding periods, from a broad August-April to a narrow February-April. Not much doubt, however, what all the to-ing and fro-ing is about.
Makes thing easier for birdos. Not so much easier for photographers, since the birds are so intensely busy and vanish in a flash. Nests, too, when built, are difficult to locate.
Got myself into great position today for the pictured bird. It struck a perfect pose. Camera - set on AI servo for tracking shots - found the low contrast and stillness too much! Perfect pose squandered! Sorry, but second-best has to do for now.
Different story, similar result with a hyperactive Fairy Gerygone (Gerygone palpebrosa).
The birds usually move through a wide variety of trees in groups of six to eight, rarely still and seldom low in foliage. (Unlike White-throated Gerygones (Gerygone Olivacea), usually in pairs, almost always in paperbarks, and scouring them from top to bottom.)
Today's solitary Fairy, busy foraging, stayed low in a small tree and near the outside of foliage close to me. Too close, in fact, since I had trouble locating the bird in the viewfinder.
In the end, no great picture. The bird was too quick and the foliage too thick. Pity, but there it is. Two almosts for the day. But two pictures to build future hopes on.
