This lovely little warbler landed in a puddle in front of me in south Texas. It exhausted my recognition techniques but I eventually by a process of elimination, decided on an Orange-crowned Warbler. I may be inaccurate and would welcome any input. Apparently the Orange-crowned Warbler has a minuscule patch of orange feathers on the crown which it rarely shows unless it raises its head feathers in agitation. This bird did not raise its head feathers, so I did not notice an orange crown on this bird, which would have made the identification much easier. It landed in the puddle, flapped and flew away.
