Migration Update & Good News about Single Dad Whooping Crane & Chick

The news thus far this whooping crane migration season, has been decidedly mixed, with an early start in some instances, slow progress in others, and what has seemed like no progress at all for the young whooping crane chicks that follow the ultralights. After such a hopeful start to the ultralight migration two weeks ago, the weather in Wisconsin has kept the ultralight airplanes, the seven young whooping cranes that follow them, and their ultralight pilot-guides and ground crews on the ground day after day in Marquette County. Those of us who live in Wisconsin are well aware how little we’ve seen of the sun since September began! It’s no surprise here that this has translated into a long string of “no fly” days. But bad weather can’t last forever – that’s the silver lining for the ultralight chicks.

And in other migration news, the official beginning of migration for the rest of the Eastern Migratory Population (the EMP) was announced at the International Crane Foundation’s Facebook page on Thursday. ICF’s Eva Szyszkoski had tracked seven of Wisconsin’s cranes to Greene County, Indiana.

Embedded in Eva’s report was the exceptionally good news that the EMP’s one surviving wild chick, and the chick’s male parent were among those cranes. There’s been little news about this special pair of cranes – the single surviving wild chick of 2014 (#w3-14) and her father (#12-02) – since late August when the sad news about the disappearance (and presumed death) or the mother crane, #19-04, was announced. (The Badger & the Whooping Crane offered some history of the crane family in the post, “A Single Parent Whooping Crane.”)

In its September Update the Whooping Crane Eastern Partnership noted that on September 8, crane w3-14 had been captured for banding (and released). Now comes this new sighting of the crane chick and the father on migration, and it’s a real cause for celebration.

Fungi and birds


Yellow staghorn, 25 October 2014

This is a photo of a yellow stagshorn fungus. We saw it today, on 25 October 2014, on an old tree stump, on Hilverbeek nature reserve.

Mycena, 25 October 2014

A bit further, more small mushrooms. From the Mycena genus? That is a very complex group.

Mycenas and moss, 25 October 2014

Still further, other, darker, mycenas(?), growing between moss.

On our way back, a robin on a fence. Chaffinches. Blackbirds in a tree.

Florida green anoles adapt to invasive species


This video from the USA says about itself:

The largest Green Anole ever!

The Carolina anole (Anolis carolinensis) is an arboreal lizard found primarily in the southeastern United States and some Caribbean islands. Other common names include the green anole, American anole and red-throated anole. It is also sometimes referred to as the American chameleon due to its ability to change color from several brown hues to bright green. While many kinds of lizards are capable of changing color, anoles are closely related to iguanas and are not true chameleons. The Carolina is a small lizard; male adults are usually 15 cm (5.9 in) long in adulthood, about half of which is its tail, and it can weigh from 3–7 g (0.11–0.25 oz). Exceptionally, these anoles will grow up to 20 cm (7.9 in) in length.

From Breaking News:

A lizard species in Florida has evolved very quickly to deal with invaders

24/10/2014 – 12:16:32

In as little as 15 years, lizards native to Florida – known as Carolina anoles or green anoles – have adapted to deal with the threat of an invading species of lizard, Cuban or brown anoles.

This video is called Egg-laying brown anole (Anolis sagrei), Aruba. This female brown anole was filmed during digging a hole in the sand in which she layed an egg.

After having contact with the invasive species, said to have first gone to America from Cuba in the 1950s, the native lizards starting perching higher up in trees. Over the course of 15 years and 20 generations, their feet evolved to become better at gripping the thinner, smoother branches found higher up.

The change was rapid. After a few months the native lizards started moving higher up the branches and over 15 years, their toe pads had become larger with stickier scales on their feet.

“We did predict that we’d see a change, but the degree and quickness with which they evolved was surprising,” said Yoel Stuart, a post-doctoral researcher in the College of Natural Sciences at The University of Texas at Austin and lead author of the study.

“To put this shift in perspective, if human height were evolving as fast as these lizards’ toes, the height of an average American man would increase from about 5 foot 9 inches today to about 6 foot 4 inches within 20 generations — an increase that would make the average U.S. male the height of an NBA shooting guard,” said Stuart. “Although humans live longer than lizards, this rate of change would still be rapid in evolutionary terms.”

This latest study is one of only a few well-documented examples of what evolutionary biologists call “character displacement,” where similar species competing with each other evolve differences to take advantage of different ecological niches.

A classic example comes from the finches studied by Charles Darwin. Two species of finch in the Galapagos Islands diverged in beak shape as they adapted to different food sources.

The researchers speculate that the competition between brown and green anoles for the same food and space may be driving the adaptations of the green anoles. Stuart also noted that the adults of both species are known to eat the hatchlings of the other species.

“So it may be that if you’re a hatchling, you need to move up into the trees quickly or you’ll get eaten,” said Stuart. “Maybe if you have bigger toe pads, you’ll do that better than if you don’t.”

The research was published in the journal Science.

Old books about birds


Pheasants, wood pigeons, wrynecks, 19 October 2014

On 19 October 2014, in Naturalis museum in Leiden, the Netherlands, there were not only the recent natural history books of the Jan Wolkers Prize nominees, and the old natural history books discussed by nominee Alexander Reeuwijk. There was also this 1904 book about birds. Again, all photos in this blog post are cellphone made.

This bird book, Het Vogeljaar (The Bird Year), is by famous Dutch naturalist Jac. P. Thijsse. In later editions, pictures like this one would be replaced by photos. This picture shows pheasants, wood pigeons and wrynecks.

Wryneck, 19 October 2014

This detail of the picture shows a wryneck.

Colourful birds, 19 October 2014

Second hand bookshop Moby Dick (called after the famous Herman Melville novel) from Noordwijk had brought late nineteenth-early twentieth century books to the museum. Like this one from 1886 by Dutch author A. Nuyens. The picture shows colourful birds: starling, red-backed shrike, golden oriole, Bohemian waxwing, jay, hoopoe and kingfisher.

Snowy owls, 19 October 2014

Next to it, this book, by Irishman Francis Orpen Morris: A History of British Birds. The photo shows a male and a female snowy owl.

Flycatchers and waxwing, 19 October 2014

A book from Germany was present as well. It was Deutsches Vogelbuch für Forst- und Landwirte, Jäger, Naturfreunde und Vogelliebhaber (1907). Kurt Floericke was the author. Albert Kull made the pictures. This page shows various Old World flycatcher species, and a Bohemian waxwing.

Cranes, 19 October 2014

Finally, a picture of cranes. Two demoiselle cranes, and a Siberian crane.

Good brent geese news


This video from Scotland is called Brent Geese – Branta bernicla.

Translated from the Dutch SOVON ornithologists:

Friday, October 24, 2014

Brent geese seem to return with quite a lot of youngsters this fall. This indicates a good breeding season on the tundra of northern Siberia. In wintering areas annually people look how many young geese will come with their parents. The geese benefited from the lemming peak at the Taymir peninsula.

Sample counts by geese counters provisionally provide an image that the brent geese had an excellent breeding success. The counters see youngster rates between 25 and 35 percent: pretty high for the brent goose. For example, there are families with five young ones, so, large families. In October, a lot of brent geese arrive in the coastal areas of Western Europe, such as the Wadden Sea. They come from the tundras of Taymir and elsewhere along the Siberian coast.

Old and new natural history books


Alexander Reeuwijk, Naturalis, 19 October 2014

This photo shows author Alexander Reeuwijk behind a table with old natural history books in Naturalis museum in Leiden, the Netherlands. Like the other photos of this blog post, this is a cellphone photograph, of 19 October 2014.

On that day, as this blog already noted, Remco Daalder, Amsterdam city ecologist, was awarded the Jan Wolkers Prize. This prize is named after famous Dutch artist and author Jan Wolkers. Natural history was one of his subjects. The Jan Wolkers Prize is for the best natural history book of the year in the Netherlands. Remco Daalder’s book is about swifts.

Remco Daalder’s book had been nominated for the prize shortlist along with four other books. One of them was Alexander Reeuwijk’s book about nineteenth century British naturalist and evolution theorist Alfred Russel Wallace and his travels in Indonesia.

The three other nominations were for Mathijs Deen, for a book on the Wadden Sea region; Bibi Dumon Tak for her children’s book on common animals; and various authors for a book on Planken Wambuis nature reserve.

Back to Alexander Reeuwijk. He presented his ten favourite natural history books from the Naturalis collections. These books were from the sixteenth till the twentieth centuries.

Pierre Belon's book, Naturalis, 19 October 2014

The oldest of Alexander’s ten books was from 1553. It was by Pierre Belon from France, about fish. Belon is often seen as the first ichthyologist. In Belon‘s time, fishes were not differentiated from aquatic mammals, aquatic invertebrates, etc. The book discussed over a 100 species for the first time ever.

The copy in Leiden is of De aquatilibus; the Latin translation of the French original.

Pierre Belon's book on sharks, Naturalis, 19 October 2014

The book contains many woodcut pictures, including of hammerheads and other sharks.

Alexander Reeuwijk’s next book was from five years later, from 1558. It was by Conrad Gessner from Switzerland.

Lobster, in Gessner's book, Naturalis, 19 October 2014

Gessner’s Historiae animalium was the first attempt to describe all the animals known. Including the lobster pictured here on a woodcut in the book.

Lobster, watercolour, Naturalis, 19 October 2014

The original watercolour depiction of the lobster, used for the woodcut, is also present in Naturalis.

Mark Catesby, parrots, Naturalis, 19 October 2014

The next book was based on two books, originally in English. Mark Catesby died in 1749. He wrote Natural History of Carolina, Florida and the Bahama Islands, published 1729-1747. George Edwards wrote A Natural History of Uncommon Birds, published 1743-1764. Catesby’s and Edwards’ books contain many pictures of birds considered as ‘exotic’ by eighteenth century Europeans, like parrots in North America and the Caribbean.

Mark Catesby's and Edwards' Dutch translation, Naturalis, 19 October 2014

Catesby’s and Edwards’ books were translated into Dutch by M. Houttuyn, and published as Verzameling uitlandsche en zeldzaame vogelen in 1772-1781.

Spotted sandpiper, Naturalis, 19 October 2014

This picture in the Dutch translation depicts, below, a spotted sandpiper from the Americas.

Alexander’s fourth book was Nederlandsche Vogelen, about Dutch birds, by Nozeman and Sepp, published in various volumes 1770-1829.

Book number five was Histoire Naturelle des plus Rares Curiosoitez de la Mer des Indes. By Louis Renard, about marine life in Indonesia. The Leiden copy was published in 1782, after the author’s death.

Next, a book about plants in the Netherlands: the Flora Batava. Jan Kops wrote the first volume, published in 1800.

Then, Histoire naturelle générale des pigeons et des gallinacés (1808). Written by Coenraad Temminck; about pigeons. With pictures by Pauline de Courcelles Knip.

Mauritius blue pigeon

One of Ms de Courcelles Knip’s pictures for the book shows a Mauritius blue pigeon; now extinct.

The next book was about kingfishers. It was A monograph of the Alcedinidae: or, family of kingfishers, 1868-1871, by Richard Bowdler Sharpe. John Keulemans made the pictures.

Then, a book from the USA, by Sherman Foote Denton. It was As Nature Shows Them : Moths and Butterflies of the United States, East of the Rocky Mountains; from 1898.

Finally, another book on birds in the Netherlands: Ornithologia Neerlandica, de vogels van Nederland, 1922-1935. Eduard Daniel van Oort wrote it. Marinus Koekkoek painted the pictures.

South African environmentalist wins award

BirdLife South Africa’s Dr Ross Wanless wins Environmentalist of the Year award

By Martin Fowlie, Fri, 24/10/2014 – 11:15

Dr Ross Wanless, from BirdLife South Africa’s Seabird Conservation Programme and the BirdLife Marine Programme, has been awarded the prestigious SAB Environmentalist of the Year Award.

Dr Wanless has overseen a number of impressive conservation achievements over the past six years at BirdLife South Africa, building on a career of seabird science and conservation work that started in 1997.

The SAB award recognises not just a lot of hard work over many years, but an individual who has been instrumental in delivering significant, lasting conservation outcomes. Very few conservation programmes can actually demonstrate tangible benefits for species they seek to conserve. It is still more exceptional for a programme to bring benefits to a suite of threatened species.

BirdLife South Africa’s extraordinary work through the BirdLife Marine Programme to prevent the extinction of albatrosses and petrels is one such example. Under the leadership of Dr Ross Wanless, the programme has used science, advocacy, persistence and win-win solutions to turn the tide against fisheries impacts on iconic seabirds. Earlier this year his team announced that their efforts in the South African hake trawl fishery had caused a reduction in seabird mortality of up to 90%. Dr Wanless is currently in South Korea, running a workshop with the Korean tuna longline fleet to assist that fleet to adopt best practice measures for avoiding accidental seabird catches.

Dr Wanless has recreated the African Seabird Group and oversaw a successful bid for the group to host the second World Seabird Conference, to be in Cape Town in October next year; he is chair of the local organising committee and sits on the World Seabird Unions’ conference executive committee. He also created and oversees the annual Celebrate Our Seas festival which kicked off in the beginning of October as part of National Marine Week. He maintains strong links to the University of Cape Town, and is currently supervising a Masters and a PhD student.

“It’s a real honour to receive this sort of recognition, but I do need to acknowledge that I have an amazing team at BirdLife South Africa, and this award is theirs as much as mine”, said Dr Wanless.
