I was not in any way surprised to see that the birds that returned to
the colony under the bridge were swallows. After all, the nests had looked exactly like swallow nests. Yet, I did get a big surprise once I started to identify the swallow species. Not only was the common Barn Swallow (
Hirundo rustica) there...

All three species had made their homes under the same bridge and were busy tending to their nests and nestlings. To be continued...
