Alameda Point Environmental Report: Least terns depart – volunteers move in at Alameda Point refuge, September 30, 2012

Excerpt:

The least tern nesting season ended in mid-August much as it usually does – a lonely and dangerous place for young terns. There were three of four pairs of adults flying back and forth with food for their young chicks. These late nesters are often the ones whose eggs or chicks were attacked by avian predators and have re-nested. Their vulnerability is only compounded as the weeks wear on because the rest of the adults and their flight-ready young have left, leaving the remaining families without the strength of numbers to mob a predator.
