Today, along with teams in a few other parts of Costa Rica and elsewhere, I will be birding for a cause, watching birds to help one that only lives in Costa Rica, the Cabanis’s Ground-Sparrow. Around the size of a Song Sparrow or Chaffinch , maybe a bit bigger, this mini towhee forages near the ground in dense scrubby vegetation.

I therefore decided to counter this month’s heinous wood-warbler attack on my retina by choosing the good old trusty House Sparrow as the topic of my May post. The last aspect is something I will elaborate on further below, but not before showing off a prime fine male House Sparrow, unethically photographed at its nest site.

A new paper out this month attempts to paint the most comprehensive picture yet of the origins and diversification of the American sparrows, wood-warblers, blackbirds, cardinals, tanagers, and their kin, an enormous group of birds more than 800 species strong.

There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. There’s more than one song per warbler? There is so much here!

These and several other species might end up being armchair ticks if and when we take a closer look at their evolutionary history. This bunch of possible Costa Rican crypto birds can be grouped into four main categories: (1). A species that lives in both Costa Rica and South America but might be two separate species. (3).

It’s mid-July, which among other things means that those of us in North America are starting to check local mudflats for returning shorebird migrants and waiting impatiently for the AOU to hurry up and create five species from the Clapper-King rail complex (the reasons for which we covered last year ). Elephant birds and their kiwi kin.
