But this time they were right at the parking lot, waiting to greet with their spectacular calls. There were males and females, and I wasn't able to make sense of exactly what they were doing--although it was, broadly speaking courtship, territoriality and other vernal exuberance-- because I was also herding humans, and there were non-associated naturalist types on site trying to take pictures--and one has to maintain a certain amount of mutual distance or be seen as an oaf. Birding isn't as simple as many would think.
I followed the flight of a little drab bird to where it landed at the top of a distant tree. I haven't figured out what it was. Almost instantly it was photobombed, then scared away by a pair of yellowheads. (In the above photo, mystery bird is below the female YH).
The whole point of going there was to see the yellowheads, and having them there right at the beginning of the walk meant that the bar was set pretty high for the rest of the day.
