From Wikipedia:

"A brood patch is a patch of featherless skin that is visible on the underside of birds during the nesting season. This patch of skin is well supplied with blood vessels at the surface making it possible for the birds to transfer heat to their eggs when incubating."

    Great capture, and educational as well (I had to google 'brood patch').

    I only learnt about them this year, but once you know, you will start to notice lots of females with scruffy-looking undercarriages in and around the breeding season. Males of some species get them too.

    Of course, now I'm anxiously looking out for signs of fledgeling bullfinches!

    I think there's another breeding adaptation visible on this, where the male has a bit of a bulge below his chin.

    Bullfinches are the only British finch to have a special throat pouch that they fill with food to take back to their young, a bit like hamsters!.

    Goodness, imagine the mischief one could get up to with a throat pouch...
