Tree Swallow, Purple Martin Egg Laying Is Up at Hammonasset, Fledging Is Down

Top line - Number of eggs laid; bottom - Number fledged

Bad weather just as Hammonasset’s tree swallow and purple martin chicks were about to fledge resulted in the deaths of many of the young birds. As a result the number of nest box success rate was down for the summer.

Of 183 tree swallow eggs that were laid, 143 hatched and 114 young fledged.

The Bridgeport Wildlife Guards, a team of students learning and teaching about conservation in Bridgeport, CT, came to Hammonasset to learn about nest box monitoring. They were able to see the difference between the purple martins’ bayberry leaf-lined nest and the tree swallows’ feather-lined nest.
