Including wing-spreading, flying and landing on water.<\/p>\n

These photos were taken 15 days ago at a local pond. Though they were all\u00a0taken within a three minute time span, each one is of a different bird (I believe). All three cormorants are sub-adults.<\/p>\n

Wing-spreading is the\u00a0classic pose of the species. It’s commonly thought that the primary reason they do it is to dry their wettable\u00a0wings but there’s been abundant speculation in scientific circles about other reasons for the behavior. After all, not all cormorant species perform wing-spreading and there is no evidence that wet wings interfere with their flight.<\/p>\n

But that’s a subject for another post.<\/p>\n

Very shortly after I photographed the previous bird I caught this one in flight as it came in to land on the water. I’ve often wondered what kinds of adjustments birds must make during flight\u00a0when they have so many flight feathers missing, as in this bird’s right wing.<\/p>\n

And soon after that I captured this one as it was about to settle into the water after touchdown.<\/p>\n

The increasing abundance of Double-crested Cormorants and\u00a0the real and perceived conflicts for resources (fish primarily) between cormorants and humans have resulted in major changes in federal law regarding their management and control. Among other methods now allowed to control their numbers are egg-oiling (used to prevent hatching of their offspring} and culling (killing)\u00a0of cormorants by tribal, state and\u00a0federal authorities.<\/p>\n

Yes, it’s controversial. Very.<\/p>\n
