With periodic spikes in the population of California Vole (Microtus
californicus) on the coast, very large numbers of WT Kites can show up.
I have seen 70+ birds in a single roost at Pt Reyes, with 100+ in that
general area. No idea what the periodicity might be of the vole
eruptions, or even if we're having one this year.
There has been a very large winter roost of WT Kites in Davis in recent
years which I am told is stable year after year. So perhaps that
concentration is due to all the good forage habitat around Davis.
