A few days ago, my caretaker availed of our nest reporting/bonus program in BK Valley, Mt. Banahaw, and reported a nest of “Arctic Warblers” with nestlings. I doubted his ID, because Arctic Warblers are migrants and I do not think they breed in the Philippines. I hoped they would turn out to be endemic Leaf-Warblers.
The nest is located in the deep shade at the base of a fern, beside the waterway at the bottom of the steep ravine below my house. The light is very poor there, and the sun never reaches the waterway because of the big trees and thick greenery of the forest. From inside a camouflaged tent, I watched both parents come to the nest with food about 5-6 times in the space of an hour. I will post photos of the parents and nestlings shortly.
Here is a photo of a parent beside the nest entrance. I believe it is a Lemon-Throated Leaf-Warbler (Phylloscopus cebuensis luzonensis) and not a Mountain Leaf-Warbler (Phylloscopus trivirgatus nigrorum), because the KG says the MW is found above 800 meters, and the BK waterway is at about 700 meters elevation. ID please.
