How Many Pelicans Can Sit On A Log?

 
Most people assume that all Pelicans live near the ocean, and, in fact, Brown Pelicans do. But the American Pelican is white, breeds on lakes throughout the northern Great Plains and mountain West, and is one of the largest birds in North America. It winters along the coasts, but breeds only inland. By October, they flock up to descend the Mississippi flyway towards the Gulf Coast to spend the winter. Reel Foot Lake is an attractive stop over point to rest and feed. All those old cypress stumps make perfect perches. And the occasional underwater log can provide perching spots for many Pelicans at a time.


Pelicans are enormous birds, with a wingspan nearing 9.5 feet, and weighing up to 20 pounds. While enjoying their wing display, I wondered why so many white birds have black wing tips. Think about it...American Pelicans, Snow Geese, Wood Storks, White Ibis, many different gulls and terns. Google to the rescue again. Apparently the melanin in black feathers makes them stronger than white feathers without melanin. It's important to have strong flight feathers when you travel as far as these birds do in migration every year.


They are graceful fliers, but getting that large body up into the air takes a lot of effort, much of it quite comical! Those big feet come in handy for a running start!

 
 



 
Their feeding behavior is different than expected too. They don't dive down into the water after fish, but swim on the surface, herding their prey into a small area to be scooped up by those long bills. Several pelicans may fish cooperatively, moving into a circle to concentrate fish, and then dipping their heads under simultaneously to catch fish. It looks like a Pelican ballet!

Summer on the Rocks



By the end of July, the water levels at the Falls of the Ohio are pretty low. This year's floods created a new sand bar just below the Interpretive Center which is  attractive to ducks, geese, and fishermen. The fishermen know to come early and leave when it gets hot, but the tourists haven't quite figured that one out yet, and they tend to arrive around 11:30, just as the heat and humidity become unbearable, not realizing that the fossils beds themselves will be 20 degrees hotter than at the top of the hill.
Local birders have flocked to the Falls during this time hoping to see the American Pelican which has been there for about six weeks now.  This is an immature bird, as evidenced by the dusky bill and dark patches on the wings. An adult will have a bill that is taxi cab yellow in color. Oddly enough, this is the third summer in which a single American Pelican has appeared at the Falls, enjoyed the fishing, then disappeared in the autumn.  Do you think Pelicans "twitter" to each other about unusual places to vacation? Otherwise, how would three different birds find out about us?  This morning, this bird paddled around fishing for a while, then spread his 8 foot long wings to fly for a while, then settled on a rock for some serious preening. The black primaries on his wings were unmistakable.  This is definitely not an Egret or some other white bird!

Reelfoot Birds

We got to see some birds not normally found in the Louisville area. Well, someone said these were White Fronted Geese exploring the lake at Big Oak State Park in Missouri. Now that I'm home and checking the field guide, I don't know what they are. Any ideas out there?
The Reelfoot naturalist let us go into the large flight cage for his two Bald Eagles, who were pretty cool about having visitors. Plenty of wild Eagles flew over our parking lot, but they were too high for good pictures.
From our weekend stay, I'd have to say that Great Egrets were the most common bird we saw. They seem very territorial. Each morning we saw an Egret on the same branches around the lakeshore by our resort. If you walked too close though, they flew off, then returned in just a few minutes.
On our hike around the edge of the lake, we saw a handful of American Pelicans preening. It looks like they are standing on water, but there are lots of submerged branches to take advantage of. It only looks like a bird miracle.
The exciting part came when hundreds of Pelicans lifted on a thermal Sunday morning, wheeling and turning until they were high enough to start flying towards their destination farther south. From one angle, there were invisible, then they turned with a flash of white wings, and the next turn made them look black. It was simply fabulous!

A Bald Eagle called while we visited, and apparently I've turned off both the recording and sound making abilities of my camera, so there is no sound. I pieced together some individual shots to get the characteristic movements. Hmm, I'll have to get into the camera setup again so I get sound with my movies.
