It's Hard To Say Goodbye

Tuesday, September 2nd was National Hummingbird Day.


Since they are one of my favorite bird visitors, I celebrated the day by hanging a brand new feeder with freshly-made nectar in it. They were overjoyed!  Well, in reality I just replaced a feeder that had cracked open and watered the pentas with sticky syrup. Ever since, the birds had been circling the empty space looking for food, so I replaced it, even though I knew they were getting ready to depart.

Like most migrating birds, hummingbirds sense when it is time to begin their long treks toward their winter nesting grounds. Scientists believe that shorter daylight hours combined with a changing angle of sunsetthe sun trigger their need to leave. Before they leave on their long journeys (some travel over 2000 miles), these diminutive birds have some work to do.

Their hearts beat at a rate of 1,260 times a minute and their wings flap up to 80 times in a second. A hefty supply of energizing fat is needed to fuel their long flights, so birds typically increase their weight by 25 to 40%.  hummer in flightIronically though, this weight gain takes place at a time when many nectar producing flowers and shrubs as well as insect populations are beginning to decline, leaving the birds with fewer food natural sources.

Here in the Midwest, there is an old wives tale still being shared that leaving hummingbird feeders up past early September will keep the birds in the area too long and they will die from our cold fall temperatures. The proof being the fact that hummingbirds  fall feeder               do appear at the feeders “past their season.” The reality is that feeders kept full of fresh, clean nectar throughout the fall --  in fact until Thanksgiving  --  are keeping migrating birds alive. Feeders left out in November may even be visited by hungry species that are usually not seen in the area. 

The migration habits of hummingbirds are different from many other migrating birds. Hummingbirds do not fly in groups. hummer in flight     They travel alone, following the same route year after year. They fly very low, just above the treetops, in order to spot familiar feeding grounds. Researchers believe that migrating birds consciously seek out the places they found food in the past, anticipating that it will be available for them again. 

Hummingbirds fly as many as 23 miles in a single day, stopping often for food. They tend to feed heavily in the early mornings, fueling up for a long daytime flight. The midday hours are their prime flying hours, and the late afternoon and evening hours are once again heavy feeding times. Hummingbirds must eat voraciously to maintain their flying weight.  hummer feeding at sunset

Sometimes inclement weather can put a temporary halt to migration. Hummingbirds have been known to stay in a “safe” area for a week or two while they wait for flying  conditions to improve. If they happen to get caught in an area during an unexpected cold snap, the birds will enter into a state known as torpor. resting hummingbird     While in torpor, a hummingbird lowers its temperature, slows its breathing and heart rate and ceases any non-essential activity, living off of its accumulated fat. Once conditions improve, the bird will resume its normal migration. Birds in torpor should be left alone; attempts to rescue it will most likely kill it.

Historically, many of the migratory hummingbirds left in early to mid August to fly to Mexico and Central America for the winter months. Today, because of climate change and warmer winter temperatures, some species are leaving later, staying put in the Gulf Coast region, South Texas and South Louisiana and heading to their northern breeding grounds earlier in the spring. feeder

The hummingbird population in the United States is thriving right now, but habitat destruction, climate change and complacency could quickly and easily change that. Let’s work together to keep our tiny visitors well fed and protected so they can continue to bring their delightful bird chaos to our yards. Keep the flowers blooming, the feeders up and the fresh nectar coming. The birds will love you for it.
