This camera was on a Red-naped Sapsucker (Sphyrapicus nuchalis) nesting hole. The Sapsucker has apparently used this tree for a few years to nest and has returned again this year to start digging out a new cavity. The camera was placed above the fresh hole, pointing down at the nesting area. Both the male and the female sapsucker have returned to the tree to continue excavating the nesting site and are extremely curious about the new camera. The Red-naped Sapsucker will dig a small cavity and lay 4-7 eggs in June or early July. Supsuckers rarely use old nesting holes, but other cavity nesting birds commonly use the old holes that the sapsuckers abandon each year.
