My morning routine has already been simplified down to the essentials – roll out of bed and out from under the protective mosquito net, pull on dirty odorous field clothes, munch down a quick breakfast. She lays an egg every day or two until completing a clutch of anywhere from five to ten eggs.
And, in SouthAmerica, there is at least one species that is being heavily preyed on by North American Minks which are not supposed to be in SouthAmerica. Their natural range is in a smallish region of southern SouthAmerica. Which brings us to the Hooded Grebe Podiceps gallardoi.
migration corridors from Argentina in the Southern tip of SouthAmerica to Canada. For example, in the Delaware Bay, warming coastal waters can cause horseshoe crabs to lay their eggs earlier than normal; conversely, more intense and frequent coastal storms can cause late spawning.
Male Phalaropes, Jacanas, Tinamous, and Rheas build nests, incubate the eggs and take care of the chicks. Perhaps the most complicated and bizarre mating system is that of the Rheas of SouthAmerica. They live in flocks in the open country shrubland of Southern SouthAmerica. Photo: Liam Quinn.
The Andean Flamingo ( Phoenicopterus andinus ) is one of the three flamingos occurring in the high Andes of SouthAmerica. Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale.
Though they weight less than two ounces, Least Terns migrate from SouthAmerica to the West, East, and Gulf Coast to breed on dunes or flat gravel roofs (there are also populations in the middle of the United States). It’s mid-April, and soon they will begin laying eggs. There is no mistaking a Least Tern: they were back!
Cliff Swallows migrate to North America from their wintering grounds in SouthAmerica to nest in large colonies, sometimes numbering in the thousands. All swallows are included under the Migratory Bird Treaty Act of 1918 as migratory insectivorous birds and as such are protected by state and federal regulations.
And, I started daydreaming about encountering something a little different, maybe a Horned Frog, Ceratophrys cornuta, a large, squat green and brown frog of SouthAmerica, with a wide mouth large enough to eat other frogs as well as reptiles. Amplexus can last from a few seconds to a few hours to a few months.
With a hardiness that belies their delicate looks (but helps explain their phenomenal success), these pioneering pigeons are already sitting on eggs at at least one location in Montana.

The Brown Pelican occurs in both the Pacific and Atlantic coasts of North America and northern SouthAmerica. They nearly disappeared from North America between the late 1950s and early 1970s because of pesticides entering the food chain. Pelicans are protected by the Migratory Bird Treaty Act.
