Maclean 1969 C. mauri 2. (6 June) Tundra on SW extension of Gasline Ridge. As before - the display was given in short bursts involving a quick flight at a relatively low height. 17 June Saw 2 birds displaying on south side of Gasline Ridge. Based on what I have seen this year, this species lacks a sustained display flight but is like fuscicollis in making short, relatively low display flights. 20 June Today there were at least 5 birds involved in a burst of display activity at the same spot. I am sure that there are eggs to be found. Did not stay to sort out the activity. 25 June Norton found a 4-egg nest by the Cake-eater site, so breeding is confirmed.
