To: Pomona
How: Volunteers of the Pomona Island Charitable trust collected 10 temporary moths placed in late July (to better cover the island for the noisiest time of year).
Thank you, it was a big ask.
Note
I have merged this data with the data from the 2023-11-02 trip, here it is for easy reference. All of this data is included in the 2023-11-02 trip.
It is possible that the high male call rates at CB11, S13T, S23, V04, which correspond with high and falling female call rates at the same locations, were incubating an egg. S23/CB11 are quite close and may be the same birds. A11 and N08M show the same pattern at a lower call rate.
