“Both heart rate and wingbeat frequency were significantly higher during ascent than later in the flight.”

“Nevertheless, wingtips remain an option as long as they aren't too chunky or thick soled.”

“It was white with long blue-tipped feathers on its crest, wingtips, and tail.”

“To do so, I would look left and right to check that the wingtips where parallel with the visible horizon.”
