Index of Subjects Hi Anna, Thanks for data, it will be entered, but is your Black Rock the one in Kings County? You can leave feeders up year round but keep them clean. Birds are always appreciative of a little help. Charles Darwin answered the question you asked about plumage since evolution of species is simply a matter of continuing to do what has worked in the past. Garish plumage tends to attract partners for males but also predators whereas camouflage plumage works best for females that sit on the nest. If a male also attends the nest then garish plumage is a bad idea since it shows predators where the nest is located. Binoculars are best chosen by going to a store and specifying a price range. The clerk lays out several pairs and you try them on targets inside and outside the store until your satisfied. Look for 7 X 42 or 8 X 40.
