Dutch Researchers Seek 2nd Dodo Species

Yesterday a team of paleontologists from the Netherlands’ natural history museum Naturalis traveled to Mauritius on a new expedition. During previous expeditions the Dutch team discovered a mass grave of Dodo bones and they are returning to the site to do more intensive research. Within the bones that were previously discovered, two distinct different sizes of birds can be identified. This indicates more than one species of Dodo.

Scientists from Naturalis and the Natural Heritage Fund Mauritius speculate the Dodo may have experienced adaptive radiation, similar to what occurred with finch species on the Galapagos Archipelago. The difference in the found Dodo bone sizes might also indicate a difference in the size between males and females of the same species. The smaller bones are not likely to be from young birds as the birds matured to adulthood after a year. The team of scientists hopes to answer the question during their expedition.

During the initial discovery of bones on Mauritius in August 2007, a total of 80 large sacks of material was removed from the site. So far half of the material has been inspected. Besides a great number of Dodo bones, material from other animals and plants was also found in the mass grave.

The cause of death for the animals whose remains were found in the mass grave is still a mystery. After the current expedition, in July 2009 the grave will be further dug out.

The team will keep a weblog during their expedition, a portion of which is available in English.

Video: White Wagtail walking on lilypads

This is another video I took during our visit to Chateau de Cheverny in France back in August 2008. There were lots of White Wagtails running around the grounds and several were hanging out at a small pond where we also saw a Kingfisher hunting. The Wagtails would fly up a few yards and then seem to divebomb back towards the water, but before hitting the surface they would slow down and land on a wooden structure that was in the water and furiously tail-wag. It was like they were trying to act like the Kingfisher by divebombing into the water.

Besides that strange behavior I also noticed a couple of Wagtails running across a patch of lilypads:

The Big Sit 2008

Yesterday we participated as Team Birdorable in the 14th annual Big Sit birding event. The Big Sit involves observing as many different bird species as possible while remaining basically in the same place. Big Sit participants find a good birding spot and remain within a 17 foot diameter circle during the event.

We are lucky enough to live within walking distance of a county preserve: Prairie Wolf Slough in Lake County, Illinois.

We arrived at our ‘circle’, a picnic table, shortly before sunrise. Our first bird was a Mallard flying over, and then the first of many flocks of Canada Geese leaving the slough for the day. Other flyovers included Herring Gull, American Crow, Great Egret and Great Blue Heron. American Goldfinches and Red-winged Blackbirds were the most abundant species.

Our total species count was 16, nowhere near fellow Illinois Big Sitters Birdfreak’s impressive total of 42. We had a lot of fun during our first Big Sit and we are looking forward to participating again next year!

Video: Kingfisher in France

Last month we visited the Loire Valley region of France. We stayed in Bourguiel and visited several chateaux, including Cheverny, which is situated on lovely grounds that included a small pond where we saw this Kingfisher hunting for lunch.

Video: White Wagtail scooting around

Last month we visited the Loire Valley region of France. We stayed in Bourguiel and visited several chateaux, including Cheverny, which has huge lawns around it. We saw lots of Wagtails there, scooting around looking for food. I took this video of one doing a really great Roadrunner impersonation.
