Деталі спостереження
An unidentified individual which I think is a dull Baltimore or a hybrid. Although Bullock's like it has a few unusual features: - lacks dark eyeline. - lacks contrasting yellow supercilium - has very broad tipped median coverts, more so than typical dull Bullock's. - Yellow vent, this is all that useful, except a gray vent is diagnostic for dull Bullock's. - greater coverts mixed, some with bold edges like Bullock's, others not. - Yellow extends lightly to belly unlike in Bullock's. Given that this bird is so intermediate, it is perhaps a hybrid. But as that is an uncertainty, I will leave it as a slash. I do not think this is a pure Bullock's however.
