Pied Cuckooshrike
Coracina bicolor
Male is a striking, heavy-billed black-and-white bird, all black above except for a large white rump, with underparts entirely white but for the dark tail. Female is similar, but gray instead of black, and has a gray throat. Juvenile resembles female but browner, with scattered white feather edgings. Pairs and singles inhabit canopy of lowland forest and forest edge. Female similar to White-rumped Cuckooshrike, but has dark eyes, is darker gray, and occupies different habitat. Gives a resonant “chew-chew-chew-chew” song as well as quieter rasping notes.

Common Murre
Uria aalge
Black-and-white seabird with crisp patterning. Dark brownish-black above with white belly. Head entirely dark in breeding plumage; nonbreeding show white face with curved dark line below eye. Sides usually show some messy dark streaks. Bill is longer and more slender than similar Thick-billed Murre; but can be difficult to judge at a distance. Also note browner plumage and streaky sides on Common Murre. Breeds in colonies on rocky islands and cliffs; spends the rest of the year on the ocean. Usually single or in loose small groups; in the Atlantic, sometimes seen in loose association with Razorbills.
Great Crested Tern
Thalasseus bergii
A large elegant tern with a very long lemon-yellow bill. Black cap does not extend down to the bill. Juvenile is scaly-looking with much more black on the back and wings. Similar Lesser Crested Tern is smaller with black cap extending down to the bill in breeding plumage. Occurs along coasts and estuaries; very rarely further inland or on freshwater ponds/lagoons.
Dusky Pigeon
Patagioenas goodsoni
This pigeon is found in the Choco region of western Colombia and Ecuador. It is fairly dull grayish-brown overall, especially gray on the head and breast with a warmer reddish tone on the nape. Compare with Ruddy Pigeon, which is typically brighter reddish on the head and breast. Most easily distinguished by voice. Dusky sings a three-note song, with a higher, longer first note followed by two shorter clipped notes: “WHOOO, whoop, whoop!” Also gives a growling call similar to other pigeons. Occurs in lowlands and foothills up to around 1,500 m. Can be fairly common, especially by voice, but sometimes is difficult to spot in the canopy.
