It seems like just yesterday we were welcoming back the warblers and other songbirds during spring migration and here we are at fall migration already.

Many of the birds we saw in the spring heading north will look the same on their southward journey. Many others, however, will look different. 

Some, like male scarlet tanagers, will bear little resemblance to what they looked like in the spring. When we saw them in May and June, they were the most brightly colored birds in the woods. A sighting always yielded a gasp of excitement as we wondered how a bird in New England could be so brilliant. After the breeding season, however, they molted and are now dull yellow with less shiny black wings. They are still awesome-looking birds but not the striking birds they were in the spring.

In addition to many adult birds molting, the fall migration includes first-year birds that haven’t attained familiar adult plumage yet. They often resemble females or a mix of male and female plumage.
