I do not know for sure if Pied-bill Grebes (Podilymbus podiceps) are migratory, but I had not seen any in a long time when I spotted a small flock of them on Tuesday in the waters off of Occoquan Bay National Wildlife Refuge. Pied-billed Grebes have a rather unusual and distinctive look—especially the bill— that makes them relatively easy to identify. Northern Virginia, where I live, is far enough south that it is a destination for some birds that will overwinter here, while many other species will pass through on their migration southward.
According to the Cornell Lab of Ornithology, “The Latin genus name for “grebe” means “feet at the buttocks”—an apt descriptor for these birds, whose feet are indeed located near their rear ends. This body plan, a common feature of many diving birds, helps grebes propel themselves through water. Lobed (not webbed) toes further assist with swimming. Pied-billed Grebes pay for their aquatic prowess on land, where they walk awkwardly.”

I’ve never seen a grebe on land, but not so long ago I found this wonderful photographic record of a western grebe trying to walk. It reminded me of all the times I’ve thought something would be a good idea, and then changed my mind in the middle of the process.
Wow. What a cool series of shots in the posting that you shared. I too have never had the chance to see a grebe out of the water and it was clear to see that its anatomy makes walking almost impossible. Thanks for sharing that link.
Great link Linda, such an interesting grebe adventure!
Nice to spot some Grebes. We have them all year round here. We do not however have any other types of Grebes.
Occasionally I will see a Horned Grebe, Eared Grebe, or a Red-necked Grebe, though the Pied-billed Grebe is the one I see most often.
And great swimmers they are, too with those feet! Grebes are fun to watch—nice capture, Mike.
