The Blackburnian warbler (Dendroica fusca) is not a frequent sighting in our area, but an adult female (I presume, after consulting The Sibley Guide to Birds) flitted between a guayabo and a eucalyptus yesterday morning. The throat was certainly more yellow than orange. I have previously identified both males and females of this species here at the house but it should be occurring here more frequently than my records indicate. The whitish stripes on the back are a good marker if you are not craning your neck upwards, which is unfortunately standard birdwatcher behaviour for warblers.
Yesterday’s other notable birds were a Slaty spinetail (Synallaxis albescens) and a pair of Yellow-throated euphonias (Euphonia hirundinacea). Here, to finish off this brief post, is a nice photo of a similar pair taken in Costa Rica by Karel Straatman:
