June is a busy month for migrant species both in the sea and the sky. Groups of humpback whales arrive from the south, following the Humboldt current past the shores of Peru and mainland Ecuador to the Galapagos.
Many migratory birds begin their journey north during June as well.
Red-footed boobies, masked boobies, magnificent and great frigate birds (on North Seymour only), Flightless Cormorants, Penguins and Greater Flamingoes breeding and nesting continue their near year-round viewing opportunities during June.
Galápagos tortoise or Galápagos giant tortoise (Chelonoidis nigra) end of mating season, beginning of nesting
The Galapagos Tortoise is the largest living species of tortoise on the planet and the animal for which the Galapagos are named, ends mating season and begins its nesting season by migrating from the highlands looking for lower altitude nesting spots where they usually lay their eggs in sandy areas. During the months of July to November, there are considerably fewer tortoises in the Santa Cruz highlands, where most travelers get to see the tortoises in their wild native habitat.
Waved Albatross a.k.a. Galapagos Albatross (Phoebastria irrorata): Nesting
In the month of May the Albatross lay their eggs, each pair producing one large white egg that is incubated by both parents for two months. June finds the Albatross minding their egg and each parent may sit for up to twenty-three days at a time. As hatching time approaches, both parents begin alternating incubation duties more rapidly so as to be prepared to feed the newly hatched chick with freshly caught food. The parents often rest very little during this period and even begin exhibiting peculiar habits such as moving their eggs around (as much as 40 meters in a few days). Eggs often end up being deserted or getting adopted by other pairs that have lost their own egg.
