Backyard birding is especially interesting during migration times — in the spring when birds are in their bright courtship plumage and males are lustily singing and in the fall as northern hemisphere migrants head back south. What causes them to migrate? It’s been shown that, at least in some birds, changes in day length cause glands in the birds’ bodies to produce hormones that produce profound changes inside the birds, changes that prepare them for the flight south. In the fall, as days grow shorter, fat accumulates under the skin. This fat contains energy needed for those coming days when the birds will be spending more energy flying than they will be eating during their occasional rests. Weather changes sometimes trigger a migration’s start, but by then the birds are already prepared.
It is especially important to have bird feeders and bird baths filled in your backyard during these migration periods. The birds will really appreciate finding food and water after spending so much energy flying. They may just take a break and let you enjoy them for a little while!

Birds are my favorite animals. That is why I love it when they drop by on my trees and sample the seeds in my birdfeeders. This site provides top quality birdfeeders and their birdbath is next on my agenda!…
