Observation details
As I started the checklist approximately 400 flew west to east over Moorland Road and far into the MMSD Wildlife Observation Area out of sight. They were in Lagoon 2, just east of Pond 3. At about 4:10pm many flew back to Pond 1 where I assume they will roost overnight - the attached recording is of this flight, and you can hear the high pitched calls of some of this year's young in a few places, most notably at 52 seconds, where you can hear it twice pretty clearly and also the sonogram signatures of these two calls (each appearing as an inverted V in the sonogram).
