River and water kingfishers nest in deep burrows dug out along streams. The burrows may extend up to 10 ft (300 cm) vertically, and from five to eight eggs are laid in the chamber rounded out at the end of the tunnel. Both male and female share the incubation duties. Many forest kingfishers nest in the same fashion as the river and water kingfishers, but some, e.g., the kookaburra, never go near the water and nest in trees.
Kingfishers are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
