Observation details

Will upload original pics later. Smaller swift with shorter tail and pale throat flying with BLSW and swallows. In the field it was the size of surrounding NRWS and TRES, and the overall darkness and fairly skinny wings/tail made me feel confident ruling out VASW. I saw a Chimney twice during my stay, assumed they were the same individual.
