Remarks :A number of migratory Oriental Reed Warblers, common at this wetland site. Many birds were actively feeding ‘together’ today as there were swarms of midges (green coloured non-biting midges that look mosquito-like in the family Chironomidae). Besides the Oriental Reed Warblers, other birds feeding on the Chironomidae include Pied Trillers, Common Ioras, Yellow-vented Bulbuls, Paddyfield Pipits, flocks of Daurian Starling/Purple-backed Starlings, Sand Martins, Barn Swallows and Pacific Swallows. Some birds were taking the Chironomidae as winged prey, especially the Swallows but the Oriental Reed Warblers were predominately gleaning them from foliage and stems of plants; often reaching upwards or downwards. The activity was fast and they allowed me to watch closely; akin to birds feeding on alate ants or termites. Prey was taken from a height of 1 to 2 meters, as the bird worked its way up and down the bushes. Rarely prey was snatched from the air. None of the Chironomidae were branch swiped, as they are rather small prey. I once spotted a daddy long legs spider (Pholcidae, cellar spider) taken. In the past I have seen Oriental Reed Warblers consume, by gleaning from foliage, 3 different types of winged Hymenoptera, one of which looked like a Wasp.
