366 of 2012 - Day 81. Red Maple (Acer Rubrum) Flowers. I don't see any signs of 'whirlybirds'. I don't recall seeing any last year, either. No signs of leaves, yet. I'll take another shot when there is change, be it fruit (whirlybirds) or leaves. It could take several weeks or several months for the whirlybirds to develop, according to Wikipedia. We shall see.
Taken with my Canon PowerShot G12, f/2.8, 1/30 sec., ISO-125, 6 mm focal length, max aperture 2.96875, no flash, camera hand held. Applied Unsharp Mask and High Pass Filter when I cropped and added text in Photoshop (details on first photo, only).
