Yungas Tody-Tyrant

A medium-sized white seabird with black marks on the wings and a yellow beak. The long white tail streamers are visible from a great distance. Nests on coastal and inland cliffs on the main islands. Often seen flying over canyons and along cliffs. At sea usually flies high above the water. Calls are loud clucks and squawks. Smaller and more graceful in flight than Red-tailed Tropicbird.

Large seabird, very similar to Masked Booby. Long and pointy on all ends: wings, tail, and bill. Adults mostly gleaming white with black flight feathers and face; note pinkish-orange (not yellow) bill to help separate from adult Masked. Young birds darker overall with brown head contrasting with white belly and dirty brown markings on underwings; very similar to young Masked or even adult Brown Booby. Found in the Pacific Ocean from Mexico to Peru where it feeds on fish; breeds on rocky islands, especially the Galapagos.

A very small, pale gray tern with large dark eyes. Smaller and paler gray than Brown and Black Noddies with slightly more of a forked tail. Nests on rocky sea cliffs on tropical islands, typically foraging close to shore, fluttering close to the water and plucking food from the surface in small flocks. Voice is a distinctive nasal “kearr.”
