Carib Grackle @ WSR |
I have been spending lots of time at the Woodbourne
Shorebird Refuge (WSR) over the last couple of weeks and it was with
astonishment that I watched a Carib Grackle’s (Quiscalus lugubris)
Colony grow from just one nest, late last year, to more than a dozen at the end
of January.

Three of the more than one dozen Grackle's nest |
Grackles are colonial breeders. So I was surprised when the first solitary
nest was built and even more surprised by where it was being built. I am accustomed to seeing these colonies high,
either in large trees or manmade structures, but this nest was being built on
drying stubs low over the waters of the east pond.

The construction of the Grackles Nest |
The nests, are open at the top, cup shape, and are made of twigs,
dead leaves and dry grass.

One of the flock of Shiny Cow Birds at the colony |
Not all of these nests will produce Grackle chicks; no
doubt some already contained Shiny Cowbird eggs. Shiny Cowbirds are Brood parasites of Grackles,
so where there is a colony, you will be sure to see Shiny Cowbirds hanging
around.
