Another fun puzzle is here. Today we feature a pair of doves building a nest in a flower filled tree. In general, the terms "dove" and "pigeon" are used somewhat interchangeably. In ornithological practice, "dove" tends to be used for smaller species and "pigeon" for larger ones. Doves are stout-bodied birds with short necks, and have short, slender bills with fleshy ceres. Doves feed on seeds, fruits, and plants. Pigeons and doves are distributed everywhere on Earth. The largest number of species is found in tropical forests and woodlands. These species may be arboreal, terrestrial or semiterrestrial. Various species also inhabit savannas, grasslands, deserts, temperate woodlands and forests, mangrove forests, and even the barren sands and gravels of atolls. This puzzle is based on a illustration by John James Audubon from his color-plate book entitled "The Birds of America".
