apparently racing, probably part of mating habits. Flying about 3 ft apart one nearly directly ahead of the other very fast, wing beats about triple normal rate, heart to tap felt at finish of down stroke like pigeons a [illegible] given a few times, flight in large arc, about 200 ft hi.
Squats about one half or one minute then a sudden relaxing & flight with & very slow deliberate strokes after a few minuter rest flight was accelerated again to racing speed but the birds then passed out of sight.
Aug 25 - Peal - I have seen this racing (described above) about 10 times in the last two weeks, usually at late afternoon or evening.
Sept. 12 - Peal - during past week much of the above racing (bright weather) often one bird makes a grunting noise with every wing beat. Usually the birds start flying abreast of each other about 5 feet apart. The stronger circles around the weaker, the radius of the circle depending on the relative rates of speed usually very wide, abt 100 yds.
Nov 14 - Wake & Peal tho the birds are not much in evidence around the compound now (because they are not mating) there is a large population - 150 or so sand flat between sand spit on Peale-Wake channel about 100 resting on sand flat at southern edge of [illegible]
