Spring: Scarlet Tanagers are common at Monticello Park each spring. These eye-popping birds breed in the Washington metro area, but they do not breed at Monticello. They usually start to arrive at the end of April, and your best chance to see one at the park is during the second week in May. They are long distance migrants who winter in South America. Summer Tanagers are infrequently seen at Monticello. They also are long distance migrants, but they have a broader wintering range that includes Central and South America and the Caribbean. A small number nest in the Washington metro area, which is near the northern edge of their breeding range, but none nest at Monticello.
Fall: Scarlet Tanagers are not common at Monticello in the fall, with an average of only 6 or 7 sightings per year. Very few Summer Tanagers have ever been seen at Monticello during the fall.
Where to See Them in the Park
Scarlet Tanagers generally sing from the canopy. Even with their bright colors, they can be difficult to find. They frequently come down to the stream to drink and bathe. Summer Tanagers behave the same way when they are in the park.
The male Scarlet Tanager is the "black-winged redbird". The body is deep scarlet, while the wings and tail are jet black. The bill is light-colored and thick, looking more like the bill of a finch than the bill of a warbler.
The red of a Scarlet Tanager is much brighter than the red of a male Northern Cardinal.
Scarlet Tanagers seem sluggish. They do not dart quickly through the trees, and when deciding whether to enter the stream, they will stay for a while either above or beside it. Sometimes, more than one tanager will enter the stream at the same time. They also are sluggish when in the stream.
Occasionally, you will see white or gray feathers on a male or female Scarlet Tanager.
You also might see some male Scarlet Tanagers whose plumage is orange, ranging from washed out orange to the orange of a bright male Baltimore Oriole. The orange feathering is caused by a condition called xanthochroism, which results from either their diet or a genetic abnormality (see Rose-breasted Grosbeak).
Female Scarlet Tanagers are olive with black wings and a black tail. The black is not as saturated as the black on a male.
Male Summer Tanagers are almost entirely red. The red is not as dark as the red on a Scarlet Tanager.
The plumage of female Summer Tanagers can vary considerably. Many females appear to be a shade between olive and yellow.
Other female Summer Tanagers look more olive brown. Female Scarlet Tanagers have little variation in their coloring. While the wings of a female Summer Tanager look dark, they are not as dark as the wings of a female Scarlet. Also, the bill of the Summer is larger and stouter than the bill of a Scarlet. The head of the Summer is flatter, but fieldmarks such as the flatness of the head can be difficult to see.
Some immature male Summer Tanagers look as if they are wearing camo plumage. They are yellowish birds with red blotches.
Fall: Adult male Scarlet Tanagers molt out of their scarlet feathers during the fall and look like females. Adult male Summer Tanagers have rosy red feathers all year. Adult female Scarlet and Summer Tanagers both have fall plumage that looks like their spring plumage.
The songs of the two tanagers are similar. The Scarlet Tanager has been described as sounding like a robin with a sore throat, and the song of the Summer is like a less burry Scarlet. It is much easier to differentiate the call notes of the two species. The Scarlet's typical call is a two-note chick-burr, while the Summer's typical call is a five-note picki-tucki-tuck. Some tanagers call more than they sing.
The North American tanagers are not related to the large colorful family of birds called tanagers in Central and South America and the Caribbean. The North American tanagers are in the same family as the Northern Cardinal. A significant part of the diet of the Summer Tanager is bees and wasps. They rub the back end of their prey against a branch to remove the stinger. A beautiful family of birds called bee-eaters in Eurasia, Africa, and Australia does something similar with the bees and wasps they catch.
