The crow is back. He’s started at three again. No, he’s gone down to two. Is he mocking me?

I am afraid of crows. If I ever have anything bad to say about them I say it in a whisper. They have a hive memory and if you cross one, the others will try to “get” you. I can’t remember where I read this – the New Yorker? – but ever since then I’ve always been careful… ; )

That was a very interesting piece and a nice observation by you. I can’t
claim that I know a great deal about the topic of counting by birds, but
crows as a group are among the brightest of all the birds. Ravens are
extremely clever and show a lot of ingenuity in solving quite complex
problems and Bernd describes some interesting examples in “Mind of the
Raven.” In addition, Clark’s Nutcracker another corvid has an incredible
ability to memorize the exact location of thousands on pinyon pine seeds
that it caches for later retrieval (often months later). But the stars of
the corvids appear to be the New Caledonian crows, which not only use
tools (rare among birds but not unknown) but can modify objects for use as
tools. So are crows as a group smart enough to be able to count? I would
think so.

I do know some other birds show the ability to count. American Coots
commonly lay eggs in the nests of other American Coots (intraspecific
brood parasitism). Recipients will toss out eggs that are dissimilar to
their own. Oddly though, they wait to throw any eggs out until they have
finished laying their clutch. So if a coot has laid a clutch of say 8
eggs, to which perhaps 3 eggs have been added by other birds, they then
are faced with a nest that contains 11 eggs. It’s been shown that the
birds will reduce the clutch down to the number of eggs they themselves
laid. This implies that not only can coots count, but perhaps they can
subtract!
