Here’s how Chattanooga penguins, birds, chimps give gifts

During breeding season, penguins attempt to woo potential mates with the gift of rocks, which — if successful — the pair will use to build their nest.

The male firefly, for instance, likes to give potential mates spermatophores, corkscrew-shaped globs of sperm and nutrients for the female to eat. Wild dolphins have been known to present biologists with dead tuna or squid. And the male great grey shrike, an adorable-looking songbird, likes to give females lizards, frogs or mice, which he first impales on a thorn or piece of barbed wire.

For more inspiration, we asked animal-keepers from the Chattanooga Zoo, Tennessee Aquarium and Reflection Riding Arboretum and Nature Center to share some of the more interesting gift exchanges they’ve witnessed over the years.

Nipper, a 13-year-old Gentoo penguin, is the best nest builder at the Tennessee Aquarium.

“He’s very picky about the rocks he’ll use. He has a knack for sturdy nests. When he gets in and out of them, they never fall apart or collapse,” says Loribeth Lee, the aquarium’s senior aviculturist.
