The Bluebird Diaries – Day 47 (May 6, 2012)

We’re giving the babies a little break from all the picture taking today. Meanwhile, we got these pictures of the mom bringing her babies a nice snack!

The thing I find interesting about these pictures, the bottom one especially, is that you can sort of see signs of her brood patch. You might remember a “brood patch” is an area on a parent bird’s belly where the feathers fall out (or she removes them) so that her skin can be right up against the eggs (and then babies). We can’t see any skin in this picture, but we can see where her feathers are disrupted. That’s the area of her brood patch. Male bluebirds do not develop a patch of their own, which is why only the female can incubate the eggs (and warm the babies before they have fur/feathers.)

We’ll be back tomorrow with another update!
