Yesterday we found a flock that contained no fewer than 7 Blackburnians, and today I saw 3 together in a mixed warbler flock, in the company of 12 Black-throated Green Warblers.
The first Blackburnian we saw on 8 April. They seem to be peaking here this week. In a couple of weeks, they will all have passed through.
The handsome Blackburnian Warbler was named in honor of Anna Blackburne (1726 - 1793), an amateur botanist from Orford Hall in Lancashire, England. A beetle and a plant were also named after her.
