Overview
Hello Ploverites!
We are now at 25 fledges for the season! The snowy plovers are once again pulling through during the last several weeks of the season. Chick survival is typically higher during the latter half of the nesting season in Point Reyes and biologists are not quite sure why. Raven activity in beach habitats tend to wind down during this time period and could possibly be an explanation. There are still approximately six to nine chicks still being raised by dedicated plover dads, which will likely increase our fledge count close to our record of 29 fledges in 2022!
One active nest remained on south Kehoe Beach last week, though it was determined to be nonviable. The adults appeared to have abandoned the nest approximately a week after it was due to hatch. Biologists continued to monitor it to see if the eggs showed evidence of hatching, but alas, they showed no sign. And just like that, no active nests remain in the seashore.
At least two of the three eggs that NPS biologists transported to International Bird Rescue last month have hatched! The chicks will be raised to fledge age with other snowy plover chicks collected elsewhere, and will eventually be released back in the seashore near a winter flock.
Winter flocks of snowy plovers continue to grow and can be found at the Abbotts Lagoon mouth, south Kehoe Beach, Limantour Spit, and North Beach. There were at least 60 plovers observed in the Abbotts Lagoon flock. Typically, winter flock numbers peak sometime in December or January, before birds begin dispersing for nesting areas in February and March.
