Rock Pigeons feed on the ground in flocks or individually. Pigeons are naturally granivorous, eating seeds that fit down their gullet. They may sometimes consume small invertebrates such as worms or insect larvae as a protein supplement. As they do not possess an enlarged cecum as in European wood pigeons, they cannot digest adult plant tissue; the various seeds they eat containing the appropriate nutrients they require.
In the Americas, the Royal Terns on the east coast, during the breeding season (April to July), occur in the US north to Virginia, occasionally drifting north to Long Island, New York. The southern end of their breeding range is Texas. The wintering range on the east coast is from North Carolina south to Panama and the Guianas, also the Caribbean islands. On the western coast of the Americas, the royal tern spends the breeding season from the US state of California to Mexico, wintering from California south to Peru.
