Bumblebee Hummingbird



Among the smallest birds in the world (2.75-3", 7-7.5 cm), the Bumblebee Hummingbird is more likely to be mistaken for an insect than for another bird. It has a short tail and a delicate, short, straight bill. Wings, back and nape green, sometimes with a bronze wash. Underparts whitish, with some chestnut on the flanks, male has a brilliant pink to purple gorget.


Chipping call, low song “sssssssiu”


Mid to upper-elevation (5000 -10000 ft,1500-3000 m)forest edges, clearings and open woodlands.


Mountains of Central and Southern Mexico.


This very rare visitor to southern Arizona flies so much like an insect that larger hummingbirds seem to accept that it is one. Rather than establishing territories of its own, it forages in other hummers’ territory, going unnoticed as an “insect”.
