JP Myers 1980 Calidris maritima tracking account Grid 3, NARL, Barrow, Alaska 17 June 1830 - Brian has been tracking this ♀ (wren) since this afternoon. Let just heard her at 1730. At 1830 as I was about to take over she flew into the territory of a ♂ adjacent to the ♂ on who's territory she is nesting. that ♂ (♂2) is now in an intense grouse display, courting wren. Unfortunately she is behind around so we cannot see how she is reacting. At 1833 ♂2 hooted over her. She did not Butt up. Before this she had been feeding on ♂2's territory. ♂2 began grooming. ♂2 flew in and disrupted the pursuit of ♂2; the two ♂'s flew off together and began a border fight, turning to parallel march within 2m of where she was feeding. They marched and they fought. After 2 minutes ♂1 flew to his territory and ♂2 began grooming to ♂1's wren. She creaved away from him, took flight, called once, she followed as she flew ~100m. There is a 2nd local female present on ♂2's territory, bathing and feeding. She then flew back to ♂2's area. SUMMARY OF 1835-1930 wren fed off away from her nest, ~300m to SE on the territories of ♂2 adjacent to the ♂ on whose territory she is nesting. After a brief flurry at the beginning of the session (actually just before it began - see McLaughlin's note + the elucidation above) she fed, rooted or pecked throughout. Then at the end she flew back to the area of her nest. 18 June Summary of 0300-0700 - Female wren remained within 100m of nest for entire 4 hr period. ♂ paid her almost no attention except for approximately 35 seconds at minute 95 and then for an intense 2 minutes at minute 214 (= 0634 am), 33 seconds of which was copulation. Not once did he hoot over her nor do a low intensity grouse display. It was all business. The copulation sequence was remarkably perfunctory from her
