In the beginning of April each year, the tufted puffins return to the Farallons. They’ve been at sea all year or as in the case of our first time breeder 3 years.The older birds that have been here before return with their mates to their prior breeding sites to attempt to raise a chick. These sites are all natural crevices in the rock, usually quite narrow and longer than the reach of the human arm.The puffins pull dry grass from the slopes and bring it into the nest site deep inside the tunnel. The male and female spend time outside their site renewing their bond - standing hunched over, facing each other with their bills together, flipping their heads back and fourth.
After billing they fly out to sea, where they will copulate and begin making that egg. The female lays a single large egg, and for the next 45 days the pair will take turns incubating. Once the egg hatches, the parents bring fish to the chick for another 45 days. So 90 days after the egg is laid, the chick fledges and flutters off the cliffs to the ocean. This is a very long incubation and nestling period for a Farallon seabird, an adaptation perhaps to variable food supply during a breeding season.
Young puffins coming to the island for the first time since fledgling fly around in groups of 5-10 birds. They compete for mates on rocky outcroppings and then investigate possible crevices with their new partners. The first year on the island the pair spends time loafing, sleeping and preening at their chosen site. Next year when they return they will come with their mate to the site they have found this year and begin the breeding cycle.
The Farallons, are the southernmost breeding colony for Tufted Puffins. It is a small tenacious group of 70-150 breeding birds that have been monitored for over 20 years. The puffins face challenges of variable food supply and warming sea surface temperatures. They have responded with boom and bust cycles, not breeding during poor food years, as well as breeding later than in the past.
Nonetheless, the puffins are a lively and joyful sight each spring and summer when they soar over the island and perch on the cliffs. They continue to return and maintain their life rituals on the Farallons, a unique and wonderful seabird we are lucky to have our offshore waters.

Wonderful minilesson on tufted puffins! Your photographs, both here, and on Photo of the Day, would make a grand book! Thank you Annie.
Is there an optimal time to go to the Farallons to see these Tufted Puffins? We have a chance to get out there on July 30th, but I think that's too late in the year to see/photograph these Tufted Puffins. Would be glad for any info. Thanks!
Nice post thanks for sharingg
