The Summer Tanager is a stout bird that searches for insects high in the forest canopy. Adult males are red, while females and young males are yellow to yellow-green.
Adult males are entirely red. Females and immature males are yellow to yellow-green; a young male in molt may show patchy red and yellow.
Summer Tanagers were surveyed at three National Wildlife Refuges in Oklahoma and Texas. May–June point counts from 2008 to 2020 recorded 12,561 birds across 85 species. A model combining the refuge data estimated Summer Tanager density at 30 birds per square kilometre, with a 95% credibility interval of 23–42.
Birds were not equally easy to detect at every refuge. The study showed that the number of point counts needed depends on both location and the precision goal. For Summer Tanagers, the estimated requirement ranged from 100 to 300 counts among refuges under the stricter precision target.
An extinction-risk assessment has not been added yet.
Across the three refuges, estimated Summer Tanager density was 30 birds/km². The number of counts needed varied by refuge and precision goal, with 100–300 estimated for this species under the stricter target. Repeated surveys that account for detectability support forest management.
