Egg-secution

Well, it’s another year without a successful Northern Flicker brood so I’ve turned off the nest cam stream. I’m not sure what went wrong. As I posted, the Northern Flicker pair laid their first egg on June 13th. A mid-June nest attempt is late, but from what I’ve read, flickers will nest anytime between March and June.

At first, things seemed to be going well. The female flicker did skip a day laying after the first egg, which can happen when there’s bad weather (usually if it’s cold and/or rainy/snowy, which wasn’t the case here), but then she reliably laid another 3 eggs over the next 3 mornings. Below is a video of her laying the second egg. The interesting thing with this female is that it was so obvious when she was laying her eggs. With the successful pair from 2016, I could only tell an egg had been laid when she got up off of them.

Then, the same day the female laid her 4th egg, the male ended up crushing 3 of the 4 eggs. I don’t know if he did it on purpose or if he was just clumsy. He certainly seemed not to be taking too much care jumping into the box! But he was also very vigilant about keeping the eggs moving rather than sitting in one spot, which keeps them viable. After the eggs were destroyed, I saw him eat bits of the remaining shells. Birds sometimes eat their eggs if they have a vitamin deficiency. Is this a clue to what happened?

After the big mishap, the female laid a new second egg, but later that same day either she or the male destroyed that egg and the remaining egg. Here’s video of one of the flickers removing the final egg after the female leaves the box.

I have a couple of hypotheses about why the birds destroyed/removed the eggs, but nothing solid. Perhaps it was too late and too hot in the season for the eggs to be viable, which the birds recognized. Or maybe one or both of the birds were sick or too inexperienced to be fit parents. Whatever the reason, there are no new flicker babies this year.
