These birds are believed to be monogamous and show no evidence of extra-pair copulation. Male Hammond's flycatcher physically fight at the beginning of the breeding season, locking themselves together in midair and fluttering to the ground. They tend to nest on high, small to medium-sized branches of tall trees. They also prefer areas where they can be covered by leaves, on the northeast or southwest sides of trees. Finally, they prefer old-growth forest, with a minimum age of 80 to 90 years.
