Peregrine at IRRI
This looks to be very similar to the birds that have been visiting IRRI for the last 2 winters. The two races that occur in The Philippines are ernesti and calidus. They're very easy to separate as ernesti does not have the white cheek patches that form the narrow tear marks so obvious in this bird.
The bird is clearly a juvenile, with streaked underparts and rufous fringes on the mantle and back. If the bird is the same one returning annually it is retaining its juvenile plumage for a number of years.
The underparts are very heavily streaked black, not the fine barring you would expect from an adult
The base colour of this bird is very pale, not what I'd expect from a juvenile...
