For example , in one study, it was found that more than 80 percent of the fledgling Australian Magpies born in a territory one year were sired by males from outside its borders. When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news!”

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. But maybe that is actually a good thing.

How to choose bird feeders; how to make nutritious bird food; how to create a backyard environment that will attract birds; how to survey your feeder birds for citizen science projects; how to prevent squirrels from gobbling up all your black oil sunflower seed (sorry, none of that works). The story of Duncraft is a good example.

Birders are always happy to see a turtle or tortoise, and there are times of the year when my social media feeds are sprinkled with photos of turtles beings removed from roads or crawling to land to lay eggs. It was fun to see both Yertle the Turtle and Teenage Mutant Ninja Turtles cited as examples of cultural imagery.

As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds.

These run the range from birds like Barnacle Goose and Little Egret, which are rare but do show up in North America every few years (actually, lately it’s been every year) to birds whose sightings in North America are so few that they’re legendary–Western Reef-Heron and Corn Crake are two examples.

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. Others invest much more effort into fewer young, giving a smaller number a much better start. Seabirds are one group of birds that go for the latter strategy.

The team explored Nevada and Utah, with Ridgway collecting thousands of bird specimen, plus nests and eggs for the Smithsonian. This is probably one of the reasons Daniel Lewis,the author,turned from writing a popular biography to a history of ornithology as a science and the ornithologist as a profession. It’s challenging reading.
