Tue, 22 May 2012 -- This morning at the Old Bridge on Potter Valley Road there were no juvenile dippers to be seen, but there was an adult sitting inside the nest and rearranging nesting material as if incubating. Is this the begining of a second brood?
Meanwhile, about 3/4 mile upstream at the Quarry Rapids, there were two juvenile dippers being fed by two adults. This is undoubtedly a different pair than at the Old Bridge.
To summarize recent activity at the bridge nest:
10 May - four juveniles left the nest and were being fed by two adults. On day one they had mastered "the dip."
11 May - one juvenile seen.
12 May - four juveniles and one adult seen below the bridge. On day three they were doing full submersion.
15 May - none seen
16 May - none seen, but an adult was seen at the Quarry Rapids.
17 May - Two juveniles seen again below bridge. Foraging on their own on day 8 on rocks and face in water. Flying well upstream and downstream.
18 May - none seen
21 May - none seen
22 May - Adult back in nest.
