The most REV.
Whilst I was REVving next door, on the summit of Pico, Philadelphia Vireo and Blackpoll Warbler were putting in brief appearances. However, both had slipped away before I popped in and my search came to an abrupt halt as news of an American Robin (first for the Azores?) crackled across the airwaves. Then, having lapped up the robin and with thoughts turning to coffee, a sparrow scooted along in front of Eric and David before putting on a display of skulking of world beating proportions,... I didn't get tickable views for the best part of four hours.
Lincoln's (Thomas not Abraham) Sparrow, presumably I was going for the ropiest photo of a 2nd for the WP ever, but I forget why now.
