OK, now you’re back. There is a very good chance you saw, or more likely heard, a Swainson’s Thrush or two while you were out there.
During late March and early April, here in Coto Brus, it seems like someone has opened up a giant firehose; and from that firehose has come a mighty river of Swainson’s Thrushes (see below).
This Swainson’s Thrush visit with us will be a fairly brief one however; for the Swainson’s Thrush is a passage migrant through Costa Rica. They have been wintering in South America and are now anxiously heading home to North America where they will build homes and raise families.
Listen for them. You’re likely to hear their flutey, thrush-like musical trill. Also, you may hear my favorite of their calls, which I call the ‘Dripping Faucet’ call. Here it is. Click on Listen (lower right) and then select the third recording from the top:
During this time of year I am always reminded of that wonderful Groucho Marx song, ‘Hello, I Must Be Going.’
Hello, I must be going
I cannot stay
I came to say
I must be going
I’m glad I came
But just the same
I must be going.
