Hummingbirds are small birds with long, thin bills. The bill, combined with an extendible, bifurcated tongue, allows the bird to feed upon nectar deep within flowers. The lower mandible can flex downward to create a wider bill opening; this facilitates the capture of flying insects in the mouth rather than at the tip of the bill.
