A Stunning Collection of Bird Portraits Explores the Nature of Beauty
Photographer Tim Flach’s new book invites us to marvel at the sheer diversity of avian species.
With their sensuous textures, striking color patterns, and whimsical highlights, birds’ beauty certainly delights us, but its real audience is birds themselves. Avian ornaments have evolved through their capacity to intrigue, entrance, inform, and attract mates. In this way, birds are agents in their own evolution.

Fall Feeding Stations
As fall colors progress southward with the cooling temperatures of October, birds that will become winter feeder visitors are working their way south too. Re-imagine your feeding station with many goldfinches, siskins, nuthatches, woodpeckers, grosbeaks, and native sparrows on hand. Plus local birds like cardinals, chickadees, and jays are scouting where reliable food sources exist as they transition from summer insects and berries to fall seeds and suet. It’s time to transition to offer “fall and winter foods” – if you haven’t already made that move. Read more from The Birding Wire HERE.
Don’t forget to check out your local Wild Birds Unlimited store for all the feeders and food items that you and your backyard birds could want. And be sure you have native plants at your home that offer fruit and berries for our winter residents and visitors. For help with selecting appropriate plants for our area, check out the Native Plant Society Chapter nearest you and the National Audubon Society Plants for Birds website.

Female Hummingbirds That Look Like Males
To Avoid Harassment
One of the most distinctive features of many birds is their colorful plumage, an attribute that scientists have frequently associated with sexual selection because it is often observed in reproductive adults: the flashier their feathers, the more likely the birds are to find a potential mate. However, after looking at over 400 hummingbirds in Panama, Jay Falk, a former pre-doctoral fellow at the Smithsonian Tropical Research Institute (STRI) and the Cornell Lab of Ornithology, suggested another possible explanation.
“In the case of hummingbirds, specifically the white-necked Jacobin that I study, males are colorful and most females are comparatively dull,” Falk said. “But if you look closely, it turns out that about one-third of female Jacobins look like males.” Oddly enough, all juvenile females exhibit this flashy plumage. Yet, as they become sexually mature, most of them lose it. So, if mating is not a priority for these young females, why would all of them exhibit the colorful feathers? Read the entire article HERE.

Why Most Birds Look Their Best in Fall Plumage
If I asked you to name the season when birds are looking their best, I suspect you would answer “spring.” That’s when most species are in their most showy and colorful breeding plumage. But I would like to make a case for fall as the season when birds are actually at their most beautiful.
Spring birds certainly capture the headlines with their bright colors and contrasting patterns. Birds like buntings, warblers, and tanagers have just returned to their nesting territories and use their brilliant color to show off for mates and rivals. The beauty of fall birds is more subtle – delicate shadings of gray and buff, crisp pale edges, all feathers new and unblemished. Read the rest of the article here.
