We started at the fish farms in Gabu, looking for the Mandarin and Black-necked Grebe that had been reported from here. No luck there, but we did find several interesting migrants, including Siberian Rubythroat, Common Teal and Eurasian Coot, as well as less common resident birds such as Golden-headed Cisticola and Philippine Collared Dove.
After a fruitless hunt for the Yellow Buntings, we went to the river mouth to look for gulls. This was much more successful as we quickly got on to a Black-tailed Gull, and then the real rarity, a possible Kamchatka Gull found by Rob Hutchinson the previous week. The birds were at a great distance, but we managed to flag down a passing banca who took us to within 50m or so of the resting birds.
In the afternoon we dropped by at Paoay lake to tick off Common Cormorant.
The following day we started with a quick trip to Pasuquin looking for forest birds, then got back to Gabu fish ponds. We were luckier this time round and quickly got very good views of Yellow Bunting. The gulls were still on the river, this time in company with 3 Black-headed Gulls.
kamtschatschensis. L. c. canus is far out of range and extremely unlikely. L. c. heinei has an almost pure white rump and upper tail, Kamchatka Gull shows brown spots or bars. This bird seems to show some brown markings, other photographs show these more clearly.
kamtschatschensis are more strongly marked than this. The underwings are very dark, much more so than would be expected from heinei. Note also the barred undertail coverts.
