Eating Like a Bird

Eating Like a Bird

Birds have much different eating habits than humans – especially during migration when they really need to add calories to deal with the stress and energy requirements of long hours of flying. You may have been chided by your hummingbird_feeding mother at one point that you ate like a bird, but if you really did, you would probably weigh a lot more than you do now! In fact, birds are infamous for eating the equivalent of what is measured in percentages of their body weight each day. Some birds, like active Chickadees might eat up to 35% of their weight daily.  An extreme example is Hummingbirds,who can eat 100% of their body weight every day in sugar-water nectar plus a couple of thousand insects. When they are migrating they can double their weight.  They need to do this as under normal circumstances hummingbirds live very much on the edge and some species feed every 15 minutes – something not terribly practical during migration or flying over open water.

Migration adds stress and uncertainly to the equation, and you will notice a difference in their feeding habits when songbirds are migrating. Since they fly at night, both in late afternoon before they take off, and early morning as they land, you can find them frantically feeding. Sometimes they are so involved in getting food that they barely will notice your presence, so there can be great viewing and photographic opportunities. These little songbirds have to do their night marathon flight and they need to be prepared to fly nonstop until dawn — so at these times, insects in flight and under leaves, beware!

Birds like endangered Red Knots, also beef up before taking off – especially the Red Knots who fly non-stop for over 8 days between Canada and South America on their route south. They are so fat they can barely take off. But when they finally land over a week later they are, not surprisingly, exhausted and starving.
Even when they are not migrating, birds really do eat a lot when compared with humans.  So when you are told you eat like a bird, you can quietly know to yourself, that probably isn’t really the case at all.
