Yellow-bellied Sapsucker (Sphyrapicus varius) Science Article 5
On 23 March 2002, in my wooded yard near Zebulon, Wake County,NC, I watched two Yellow-bellied Sapsuckers (Sphyrapicus varius), a maleand a female, engage in behavior I had never before witnessed. The malewas perched on the trunk of a small hickory (Carya sp.) having bark riddledwith sapsucker wells.
