The first bird (which I saw if this was taken at the upper reservoir) I believe is a Two-barred Greenish Warbler. Note the the long bill, almost entirely pale lower mandible and two wingbars. There was also a Pale-legged Leaf Warbler in this area as well.
The second bird looks more like Yellow-browed. The bill is short and appears to be rather dark on the lower mandible.
