The Three-toed Woodpecker is the most often spotted woodpecker here in Banff National Park, found year around. Boreal forests and montane coniferous forests is their preferred habitat. Diet preference are insects, dominated by wood-boring beetle larvae, also happy to eat fruits and feed on tree sap. So the nest time you are in their habitat and hear a soft chipping sound, stop, locate the direction of the sound and step over to watch the woodpecker scale off flakes of bark to get at insects.
Until next moment,
