Tanagers are a group of birds known for being extremely bright. These members of the cardinal family have thick bills and are medium distance migrants. In the United States there are four different species of tanagers, and three of them can be found in Iowa with two being common visitors and the other being rare. Here is everything you need to know about these three species.
Scarlet Tanager
Identification
Male Scarlet Tanagers are bright red with a slight orangey shine when viewed in bright sunlight. They have inky black wings and a black tail. Females are a brownish yellow color with their wings and tail being a darker shade than the rest of their body.
Range
Scarlet Tanagers winter in western South America and move through the eastern United States in spring. This species spends the summer in the northeastern United States including New England, some states in the Midwest, and even some of the more southern states such as Tennessee, northern Georgia, and northern Alabama.
Diet and Foraging Habits
Scarlet Tanagers are mostly insectivores eating a wide variety of different larvas and adult insects. This species will also eat tree buds in the early spring and fruit including berries such as mulberry.
Where to Find this Bird
Scarlet Tanagers are birds of deciduous and mixed deciduous forests. They will make stops at a variety of different habitats during migration including backyards and parks (especially if there are berries to eat nearby). Scarlet Tanagers usually reside high up in trees, so keep an eye out for an extremely bright red bird in the canopy.
Summer Tanager
Identification
Adult male Summer Tanagers are a deep red color. Immature males are a mix of yellow and red with red feathers coming in to replace the yellow as they molt. The more yellow, the younger the bird is. Adult females are completely yellow bodied with darker coloration on the wings.
Range
Summer Tanagers winter in northern South America, Central America, and Mexico. In spring they begin their journey north, ending up in the southern United States. The Summer Tanagers range extends farther north in the eastern U.S. than the western U.S. reaching as far north as Ohio and Iowa.
Diet and Foraging Habits
Summer Tanagers eat many different insects and other invertebrates. Some of their most preferred foods are bees and wasps. They will catch them out of the air and then rub the stinger off before consuming them. Other items on the menu are various fruits such as mulberries.
Where to Find this Bird
Summer Tanagers are typically found in deciduous woods with moderate tree cover. They also live in places like forest edges, backyards, and parks. During migration this species will appear in mixed forests and along lake edges along with warblers, grosbeaks, orioles, and other tanager species.
Western Tanager (Rare)
Identification
Male Western Tanagers are arguably one of the most beautiful bird species in North America. The are bright yellow with a reddish orange face, and black wings with a yellow shoulder marking. Females are slightly duller yellow with grayish black wings and tow light wing bars.

Western Tanagers winter in Central America and Mexico. They migrate north in spring and breed in the western United States and southwestern Canada.
Diet and Foraging Habits
Western Tanagers have varied diets that differ depending on season. In spring and summer, they feed primarily on different insect species including dragonflies, grasshoppers, and wasps among others. In fall and winter, they switch over to eating primarily fruit.
Where to Find this Bird
Western Tanagers are typically found in mixed deciduous and coniferous forests as well as forest edges, parks and backyards. They also live in drier areas such as scrub and elevated pine forests.
Summary
Tanagers are among the most colorful migratory bird species in all of North America. Knowing which species are common or rare for your state and region can be instrumental in correctly identifying these brightly colored birds in the field.
