Black-capped Chickadee and Dark-eyed Junco are both common birds in the Coastal Western Hemlock zone. The two species can co-occur in the same
Habitat
because they occupy a different
Niche
Chickadees are typically found foraging on
tree branches
for insects, seeds berries and other food items
and juncos usually forage on
for
Nevertheless, there is is some overlap between
the life history of these two species.
Based on the information you have read, where might you predict that you will be most likely
to observe juncos versus chickadees.
Bushtit are another common species that exploit a similar niche to Black-capped Chickadee.
They likely persist in the same environment because they exploit
tiny insects
Think about what you would record if you were observing birds to determine whether they
were more abundant in one habitat than another, whether they differed in their habitat choice
from other species, and whether they exploited a different food source within a very similar
habitat.
