Bluish Flowerpiercer Diglossa caerulescens


Diet and Foraging


The main diet of the Bluish Flowerpiercer is nectar from canopy tree flowers (Hilty and Brown 1986), as the name suggests. However, this particular group is known to also “glean for insects and eat some small fruit” (Ridgely and Tudor 1989). Isler and Isler (1987) examined 8 stomachs: 6 had animal matter, 1 had plant matter and 1 had both plant and animal contents.
Behavior-The Bluish Flowerpiercer forages in the canopy (Parker et al. 1996), which means it scans the near top and crowns of trees to find its food. This bird is usually found alone or in pairs, and most often in mixed flocks (Hilty and Brown 1986). Also some researchers have noted this bird to be “restless, active, and somewhat aggressive” in temperament (Isler and Isler 1987).
