I have three hummingbird feeders hanging underneath the eaves of the house very close to glass doors where I can stand among them while they whirl around my head. For the last two months I have been noticing one or two ratty looking birds in molt that had what looked like white feathers on the crown. I thought it was pollen until one came to the feeder so close I had to refocus my eyes. It was definitely white feathers thinly covering the head. Then yesterday I saw an adult male, fully feathered, with a bright white patch on the forehead. It was about ten inches from my face. I don't remember seeing this in the past. I'm sure they were Ruby-throats. Robbie Hassler Byrdstown, TN Pickett County
