The list below shows the 101 birds you’re most likely to see on Cape Cod, plus a few birds so iconic to the area it would’ve been a shame not to include them, too. For each listed species, you’ll find:

• An illustration: Including (if necessary) symbols that explain if the birds within a species look different from each other based on geographic region, sex, time of year, age, or other factors.

• Key stats: Average length, weight, and wingspan

• A Presence Indicator: A color-coded month-by-month breakdown of when that species is or isn’t present in Cape Cod (the darker the color, the more abundant the bird is in that month).

The birds are listed in order of length, from smallest to largest. Filters on the page let you re-order the list as you prefer.
