The ducks and geese have paired up for the spring, and you know that this means! Goose attacks are going to be pretty likely. Don’t get Tyrannosaurus rek’d by a goose. They can be very aggressive, especially when nesting.
An adult goose can weigh 15 lbs, so be careful.
As for the ducks, here’s a fun experiment to try. Go look at some mallard ducks. You can find them in parks with ponds, or other places near water. Usually, the males have green heads. Compare the number of males (drakes) to the females (ducks). Notice anything unusual? I’ll hide what you’ll probably find out in this bracket, in white text. Click and drag between the brackets to reveal the spoilers. [ There will probably be more drakes than ducks, by a pretty large margin. ] Weird, huh. Why do you think that is? Click and drag for the answer.
[ Females sit on the nest and are more vulnerable to predators, which probably leads to to the sex imbalance. Birds have a similar sex determination system to us mammals, so you can assume that there’s an even number of male and female ducklings hatched. ]
And that’s not all the duck weirdness going on. If you saw the ducks at just the right time, in mid-summer, you might not have noticed any drakes at all. Ducks moult completely, losing all their feathers, and, while they grow back in, they’re flightless, and very shy. Right after this, and before growing in their breeding plumage for the fall, the drakes’ feathers come in looking just like a duck. This brief, non-breeding plumage is called eclipse plumage. The only way to tell while the males are in eclipse is that male mallard ducks’ bills are yellowy or olive, not orange-y black.
If you want to take your bird-observing to the next level, check out the Bird Guide from the Cornell Lab of Ornithology. Or, check out a handy, portable, and comprehensive identification key from the library. Ducks are really odd, actually. If you want to do more than dabble in a different sort of dabblers, read this book for a deep dive into the wood ducks, the most fabulous of all ducks. Ducks and geese hatch ready to follow the parents around, and start life out with a leap from the nest. Watch hooded merganser ducklings take the plunge.
