This is from Birds of North America account for Chuck - length 28-32 cm, with wing 20.0-22.5 cm and tail 12.8-15.1 cm; mass about 110 g, males with white on inner webs of outer 3 rectrices, which are tipped with cinnamon-buff (white patches visible on dorsal surface of tail when spread); female lacks white in tail. Sexes otherwise alike in appearance; male averages slightly larger than female (considerable overlap, however): wing on male 20.5-22.5 cm and on female 20.0-21.9 cm; tail on male 13.4-15.1 cm and on female 12.8-14.4 cm. For the Eastern Whip-poor-will - Medium-sized nightjar, 22-26 cm in length, 43.0-63.7 g body mass. Here's some info on Chuck behavior: Typically silent flight-numerous flaps and a glide. When prey, usually a flying insect, is encountered, opens mouth quickly, sometimes with a quick dive and chase when additional pursuit is required. These flights take place at heights ranging from a few meters to about 20 m above ground. Shorter flights or sallies also made from exposed perches into open air space to capture prey, followed by return to the same or a different perch. High buoyancy index, large wings and tail, and relatively large pectoral muscles and aspect ratio suggest a flight with quick maneuverability and frequent glides Males chase one another during territorial disputes. Chasing is accompanied by Growl. Females known to chase males, possibly in mating events.

We stopped there last night (Monday) on our way home from Madison to Medford. We arrived just after 8:00 p.m. and first heard Whip-poor-wills about 8:30 or so. At about 8:45 we heard the Chuck-will's-widow quite far to the northwest. About 9:00 a Whip-poor-will started calling almost overhead on the south side of the road, followed shortly thereafter by the Chuck-will's-widow very close to us on the north side of the road. The latter moved among several trees. Then, while it was still light enough to see silhouettes, we saw two nightjars, one chasing or following the other, fly from the north side of the road to the south, circle around a tree, and disappear. This flight was accompanied by what I think was wing-clapping. There appeared to be a noticeable size difference between the two birds, and, since I cannot find any indication in field guides or on the internet that there is a size difference based on gender, I suspect one bird was the Chuck-will's-widow and the other was a Whip-poor-will. We stayed about another five minutes or so but did not hear either again. FYI, there were almost no mosquitoes, unlike previous years when I've been there. Not to say there won't be.
