Palm Warbler — Setophaga palmarum
This warbler is an early spring migrant. It is brownish above with dark streaks over yellow below. The male has a chestnut colored crown. The female lacks the chestnut coloring and is rather none descript. This warbler constantly bobs its tail and often may be seen feeding near the ground. It nests in coniferous bogs in Canada. At other times, it may be found in small groups on grassy or weedy open ground.
