Probable cause…

Observation date: 19 July 2015

A summer thunderstorm hit the Central Coast of California last night and today leaving a much needed inch and three quarters of much needed rain.

Aside from the good quenching in drought ridden California, it gave us some probable answers as to why the south side pair of falcons could have had a failed nesting.

The last rain we had was in the spring when she was incubating or could have had hatchlings. Today looking at the upper five eyrie, this year’s nest site, there is an obvious stream of water pouring into this hole. It was not noted in the previous rainstorm as no one came out to watch the falcons.

Both adult pair of falcons are now molting, one feather on each wing missing and one tail feather. This will continue until all are replaced. The juveniles will not molt until next year at 13 months of age.

Happy trails, Bob
