The Wisconsin Department of Natural Resources held an online chat about whooping crane migration and other related issues last week. It took place at noon, October 31st.
It was one of the DNR’s series of Ask The Experts online events, where various DNR staff take part in discussions and answer questions about their topic of expertise. There have been sessions on walleye fishing, deer hunting, well water testing, beach monitoring, and so many other topics.
For the Whooping Crane version of Ask The Experts, Davin Lopez – the DNR’s whooping crane coordinator, was joined by 2 other partners in the whooping crane reintroduction efforts in Wisconsin. Joan Garland, outreach coordinator for the International Crane Foundation, and Heather Ray, associate director of development for Operation Migration, joined Davin in typing back answers to the questions almost as fast as we online chatterers submitted them.
Midway through the chat we learned that there were approximately 100 who were participating! As a participant you have no idea that you are part of such a large virtual audience.
Among the many dozens of questions that were asked, the topic that attracted the most attention – at least 12 questions and comments – was concerned with treatments to reduce the Black fly population (which seems to contribute to the cranes abandoning nests at breeding time) at Necedah NWR. I’ll add a separate post about that, but first, here is a list of some of the topics touched on:
– Although the ultralight-led migration began for this year’s crop of new cranes on October 2nd, there have been no reports of “on migration” sightings of any of the 100-plus adult whooping cranes in Wisconsin. Heather Ray said that generally they don’t begin migration before November.
– She also said that the ultralight migration flights begin with short flights of 5 to 20 miles in distance and gradually expand to 50 and 60 mile flights, as the birds gain experience and stamina.
Efforts to train whooping cranes to migrate with ultralights begins when the colts are very young.
– The goal of the whooping crane re-introduction campaign in Wisconsin (technically the campaign is for the entire Eastern half of North America, but Wisconsin is key, as the northern terminus of the flyway that is being established) is 100 individual birds (that goal is within reach) and 25 successful breeding pairs (not even close); actually, Davin Lopez called this “a very rough goal . . . what we need is a self sustaining, growing population.”
– Ray reported that there were 20 breeding pair in Wisconsin in 2013. Unfortunately only 3 chicks hatched from these nests, and only one has survived to fledge. (The survivor is designated #W3-13 – the 3rd chick hatched in the wild in 2013 – and will be migrating south with its parents: #9 from 2003, and #3 from 2004).
– Except for 3 surviving wild chicks (the 2013 survivor, and #w1-06, and #w3-10) all of Wisconsin’s wild whooping cranes were hatched from eggs produced each year by the captive populations at ICF and Patuxent Wildlife Research Center in Maryland. Ray said that there are generally 30 and 40 eggs available each year from these sources, and they are split 50/50 between Wisconsin and the new <strong>Louisiana Non-migrating flock; efforts to establish this were launched in 2011.
– One participant commented about a Sandhill Crane hunt, which has been rumored for Wisconsin. He suggested that it would be hard for hunters to distinguish between young whooping crane colts and Sandhills. Joan Garland referred him to a fact sheet at the International Crane Foundation website that addresses the hunting proposal.
– As the chat closed, another guest added this personal note: “Thanks to a school presentation by Joan, my son is hooked on the whooping crane and he wants to be a biologist when he grows up!”
How lucky, that courtesy of the International Crane foundation, I just happen to have a picture of Joan making such a presentation! And here it is:
