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.
