Gentoo Penguins, Petermann Island, Antarctica

The Gentoo Penguins (Pygoscelis papua) become smaller the further south they live. Their slaty-black heads are topped eye to eye with a neat white bonnet, and they have a bright reddish-orange bill. Long, stiff tail feathers stick out as they walk, often cocked up in the water. No other penguins have such a prominent tail.

Gentoos on the peninsula return to their breeding grounds on flat areas on rocky coasts in October/November. Their attachment to a nest site is not strong as there is usually no shortage of possibilities, but their pair-bond is strong and they usually mate with the partner of the previous season.

Parents share an incubation period of 31-39 days, and the chicks are fed on undigested shrimps or small fish by regurgitation. They gather in the protection of crèches at four to five weeks allowing both adults to go fishing and fledge in about 62-82 days in the south. Uniquely among the penguins, the young continue to be fed for a gurther period by their parents after fledging, so that they are hanging around the moulting area together will into March. The total population of Gentoos is somewhere around 400,000 pairs, most living south of the Antarctic convergence, mainly on South Georgia. They are currently increasing in range both in the Falklands and the Antarctic Peninsula where these photos were taken. – Antarctica a guide to the wildlife by Tony Soper.

These penguins take advantage of stream-lined bodies and strong “flippers” in the water to dive more than 600 feet deep and swim up to 22 miles an hour, the fastest of any other diving bird. – Oceania.org

Adelie Penguins

Adélie Penguin, Petermann Island, Antarctica

Along with the Emperor , the Adélie is the only other truly Antarctic penguin. It breeds further south than any other penguin. The body and head are all blue-black, the bill is reddish with a black tip, and the eye is ringed in white. The classic “little man in evening dress”, the Adélie is the littlest species of penguin in the Antarctic. It might look cute and a bit clumsy on land but don’t be fooled, these birds are feisty. They’ve been known to take on potential predators – seals or large seabirds – or even attack visiting researchers with their flippers.

At sea its cruising speed is about 7.2 km/h (4.5 mph). The maximum recorded fishing dive was to 175 meters (574 feet). They feed mostly on crustaceans, the rest fish and cephalopods (though mostly krill along the peninsula).

On their breeding grounds, Adélie s experience the coldest Antarctic conditions and enjoy the shortest summers. The whole breeding cycle has to be fitted into the few weeks when temperatures rise above freezing and when food is abundant in open waters not far away. The typically dense colonies are established on the ice-free slopes of rocky coasts, headlands and islands, on high ground, often far from open water but offering a practicable route to the sea. The critical requirement is that there should be open water within a few miles in the January/February period when chicks need regular supplies of food.

Adélie penguins are increasing in Antarctica. However, in areas where climate change is established, Adélie populations have fallen by more than 65% in the past 25 years. The biggest threat to them right now is climate change (other penguins, like gentoos, are better adapted to warmer climates).

A Band-tailed Pigeon
A large swift and handsome bird
A wonder to see.

These awesome looking birds are usually seen at a higher elevation. It is the first time I’ve ever seen one at my place. Band-tailed Pigeons can be found in two separate regions in North America: dry mountain forests of the Southwest and wet forests of the Pacific Coast.

Gave a talk at the college
Grace personified

Terry Tempest Williams was here in Durango this weekend at a Climate Change Summit.  I sat up front and was able to grab a cell phone photo of her immediately after her talk.  At the end of the day, I showed the photo to her husband.  He liked it and I emailed it to him.

She ended her talk with a quote from her 2020 essay “A Burning Testament” about the wildfires out west:

“Grief is love. How can we hold this grief without holding each other? To bear witness to this moment of undoing is to find the strength and spiritual will to meet the dark and smoldering landscapes where we live. We can cry. Our tears will fall like rain in the desert and wash off our skins of ash so our pores can breathe, so our bodies can breathe back the lives that we have taken for granted.

I will mark my heart with an “X” made of ash that says, the power to restore life resides here. The future of our species will be decided here. Not by facts but by love and loss.”

Hand on my heart, I pledge of allegiance to the only home I will ever know.
