Alamootie update

Out of 165 nest sites that were identified with singing birds in at the beginning of the season, 67 have had an egg laid in them and 25 of those have hatched in the last 2 weeks. About 10 eggs have been lost, so there are hopefully around another 30 eggs waiting to hatch. Chicks that have been left alone by the parents so far, have weighed in at between 13 and 22 g and the tarsus measuring between 13.6 and 17.7 mm long. These chicks have been between 7 and 14 days old. Since chicks don't fledge until they are at least 50 days old (and possibly even until around 70 days old!), the first chicks will not fledge until the beginning of September at the very earliest. It's certainly a long season for the stormies and anyone studying them!
