By contrast, 55% of all American Yellow Warbler nestings are successful in raising at least one young.

Males court the females with songs; an American Yellow Warbler has been observed to sing more than 3,200 songs in one day.

The American Yellow Warbler is sometimes colloquially called the "Summer Yellowbird".

However, especially American Yellow Warblers are prolific, and the stocks will usually rebound quickly if riparian habitat is allowed to recover.

Above, the North American yellow warbler plays host to a brown-headed cowbird chick, as well as raising her own hatchlings.

In particular American Yellow Warblers will come to suburban or less densely settled areas, orchards and parks, and may well breed there.

Other invertebrates and some berries and similar small juicy fruits are also eaten, the latter especially by American Yellow Warblers in their winter quarters.

Very few if any American Yellow Warblers breed more than once per year; around one in twenty Mangrove Warbler females will do so however.

A wintering American Yellow Warbler examined near Turbo, Colombia was not infected with blood parasites, unlike other species in the study.

The breeding habitat of American Yellow Warblers is typically riparian or otherwise moist land with ample growth of small trees, in particular willows (Salix).

Adult American Yellow Warblers are significant dispersers of plants via the ingested seeds, though this may of course spread any invasive weed whose fruits they find tasty.

The American Yellow Warbler (Setophaga petechia, formerly Dendroica petechia) is a New World warbler species.

They are, like most songbirds, generally serially monogamous; some 10% of Mangrove Warbler and about half as many American Yellow Warbler males are bigamous.

American Yellow Warblers breed in most of North America from the tundra southwards, but they do not range far southwestwards and avoid the Gulf of Mexico coasts also.

The American Yellow Warbler (aestiva group; 6 subspecies breeds in the whole of temperate North America as far south as central Mexico in open, often wet, woods or shrub.

Almost half of the parents (somewhat more in the Mangrove Warbler, somewhat less in the American Yellow Warbler) attend the fledglings for some time after these leave the nest.

The odds of an adult American Yellow Warbler to survive from one year to the next are on average 50%; in the southern populations, by contrast, about two-thirds of the adults survive each year.

American Yellow Warblers arrive in their breeding range in late spring - generally about April/May - and move to winter quarters again starting as early as July, as soon as the young are fledged.

Conversely, less than one American Yellow Warbler nest in three on average suffers from predation in one way or another, while two out of three Mangrove and Golden Warbler nests are affected.
