There’s More Than One Way To Catch a Wolf!

The first attempt at finding a den this year offered the Red Wolf Recovery Program biologists a new challenge. Finding this particular den was going to be easy….it already had been spotted from the air during a telemetry flight. The challenge in this case was that we wanted to get our hands on the mother as well as the pups.

Female wolf 1686F was wearing a radio-collar that was near the end of its battery life. We needed to change her collar to prevent losing radio contact with her. The conventional method for catching a wolf to change its collar is to set modified leg-hold traps. For a mother with young pups, however, that’s not an option because there is always some risk involved (albeit small given the design of the trap). Instead, we decided our best option would be to sneak up to her den without being detected and capture her in a net as she exited. As you can see from the photo every once in a while a plan comes together!

Once her collar was replaced, we processed her pups, placed the pups back in the den, followed by mom, and moved on to our next den search.

2011: A Good Year for Red Wolf Recruitment

As the 2011 denning season winds down for the Red Wolf Recovery Program, the tally of red wolf pups born in the wild appears to be 46. This was an unexpectedly strong year for recruitment in the wild population. The number of mortalities of breeding wolves in recent years presented a challenge in optimism going into this year's denning season. Fortunately, 11 pairs of breeding wolves, including seven newly formed pairs and first time breeders, gave us a lot to be optimistic about.

Celebrate Endangered Species Day 2011

On 20 May 2011 the Red Wolf Recovery Program and the U.S. Fish and Wildlife Service will observe Endangered Species Day.

Endangered Species Day is an opportunity for people young and old to learn about the importance of protecting endangered species and everyday actions that people can take to help protect our nation’s disappearing wildlife and last remaining open space. Protecting America’s wildlife and plants today is a legacy we leave to our children and grandchildren, so that all Americans can experience the rich variety of native species that help to define our nation.

Started by the United States Senate, Endangered Species Day is the third Friday in May. Every year, thousands of people throughout the country celebrate Endangered Species Day at parks, wildlife refuges, zoos, aquariums, botanical gardens, libraries, schools and community centers. You can participate in festivals, field trips, park tours, community clean-ups, film showings, classroom presentations, and many other fun and educational activities.

In partnership with the Endangered Species Coalition and the Association of Zoos and Aquariums, events will be scheduled throughout the country. Go to www.endangeredspeciesday.org for more information on Endangered Species Day events near you!

Where there's a Will, there's a way.

Having the chance to ride along with the Red Wolf Recovery Program biologists a few weeks ago as they began their annual search for red wolf dens, I can back up Ryan’s recent blog postings that finding dens takes a great deal of patience and effort. After the first few days I wondered if the biologists were setting me up by looking for dens in locations that could test the abilities of a triathlete. However the reward of finding a litter was well worth the briar scratches and tick plucking, and it was apparent that these kinds of areas provided the wolves needed cover and security as they go about the business of rearing their young.

With the miles of dirt roads, fields, and drainage ditches it’s easy to get disoriented as the biologists rattle off the name of this or that pack, road, or location. Radio telemetry no doubt helps, but when combined with their experience, knowledge of the area, and an uncanny sixth sense, the crew has remarkable success locating dens.

As coordinator for the Red Wolf Species Survival Plan, being able to help search for wild dens gave me the opportunity to take a step back and look at the Red Wolf Recovery Program from a “big picture” perspective. It also underscored that there are many individuals, agencies, and organizations committed to ensuring that red wolves will continue to thrive. -- Will

A Wolf Named "Willy"

During the third week of April, in the midst of our annual search for red wolf dens, biologists with the Red Wolf Recovery Program were accompanied by a special guest, Red Wolf SSP (Species Survival Plan) Coordinator, Will Waddell. Will, based at Point Defiance Zoo and Aquarium in Tacoma, Washington, has been leading the red wolf captive-breeding effort for nearly 20 years. In doing so, he has been involved in the birth and care of countless litters of captive red wolf pups. But, surprisingly, he has never been involved in the finding and processing of a litter of wild red wolf pups. This particular denning season he was able to lend the field biologists a helping hand, and we were more than happy to have him on board.

After a lengthy, hot, and unsuccessful search amidst a large block of pine trees and tangles of briars on the first day of Will's visit, Day 2 proved to be much more rewarding. The den was located under a grove of myrtle bushes in the middle of, what else, a large patch of briars, to a first time mother. Although we were hoping for a litter from her this year, we weren’t really counting on one because of her young age. So, finding that she had had a litter, even though it was only one pup, was a pleasant surprise. After realizing the healthy week-old pup was a male, Will declared “We’ll have to call him Willy!”

Technically, red wolves are not given names, and this pup will be no different. Rather, he will be assigned a studbook number (by his namesake, ironically) to which he will be officially referred. But unofficially, he may very well be known for some time by the Red Wolf Recovery Program biologists as the wolf named “Willy”. -- Ryan

Denning Season Is Here Again

It’s that time of year again. The days are growing longer and notably warmer, and field biologists with the Red Wolf Recovery Program find themselves spending the majority of their days climbing, crawling, and wriggling under the hot sun through some of the most inhospitable habitat imaginable. Ticks, chiggers, horseflies, poison ivy, and entanglements of briars are just a few of the obstacles in their path as they embark on this year’s search for a fuzzy new generation of red wolves. Despite the unpleasantries, denning season is without a doubt the highlight of the year for biologists. It is this new recruitment of red wolf puppies each spring that essentially represents the fruits of the previous year’s labor. Each year, the number of new wolf litters allows biologists to gauge how successful the previous year’s efforts were in trapping and tracking wolves, dealing with mortalities, forming new pairs, and preventing hybridization.

This year’s den search got off to a nice start. The first two litters found were of partially unknown parentage. Of course, the maternal sides of the pups’ pedigrees were known. It was the paternal side that was in question. Fortunately, blood results indicated that the puppies from both litters were indeed pure red wolves and not wolf/coyote hybrids. This was great news, and it gave us a new sense of optimism right out of the gate regarding this year’s denning season. Adding to our optimism was the fact that both of the females were first time mothers, having taken over as the new breeding females after the deaths of their own mothers. We weren’t sure if we would get litters out of these females this year, so again, it was a great start.

The next litter discovered was from the Milltail Pack on Alligator River National Wildlife Refuge. There were no pedigree questions here as we knew who both parents were. And it was even more good news when we found seven healthy puppies. An average red wolf litter is four pups, so a litter of seven is always a welcome sight.

Additional litters were found during the next several days; the current count stands at nine litters and 37 pups, with a few more possible litters yet to be found. Following a tough year of losing a number of breeding wolves due to premature mortality, this is shaping up to be a surprisingly good year of pup production. -- Ryan
