It’s hard to resist laughing at some wildlife photos.   

Judging by your response to our first installment of amusing wildlife photos that we shared back in August, you agree.

So we’re sharing a new group of chucklers.

It shouldn’t come as a surprise that most were taken at national wildlife refuges. Where better than refuges to spot so many birds and animals in the wild?

The Night Lives of Forest Elephants

“Elusive megafauna” may sound like an oxymoron, but in the case of the Congo Basin’s forest elephants, it is not. Dr. Peter Wrege of the Cornell Lab of Ornithology’s Elephant Listening Project has been recording the sounds of elephants for 10 years in Central Africa, often in natural clearings called bais, where elephants gather to socialize and drink mineral-rich water. Observing large mammals in clearings may sound easy, but 80 percent of elephants’ activities at bais now take place under cover of night, a shift in behavior in response to human activities in the daytime. In addition, elephants communicate using a range of vocalizations, most of which are below the range audible to human ears.

To reveal what these secretive giants are doing in the dark, Wrege devised audio recording devices to listen to elephant calling activity and deployed night vision and thermal imaging equipment. Bais are hotspots of elephant activity, but unfortunately they also attract humans – poachers in search of ivory. Thanks to acoustic monitoring, Wrege can not only determine how many elephants are visiting a bai and when, but also detect poaching attempts (by recording gunshots) and the impacts of human activities such as encroachment from logging operations and oil exploration. Wrege and colleagues engage with governments, logging companies and local communities to continuously monitor and secure the most important bais.

AUDIO
  • Elephants at a bai

Wrege’s ongoing acoustic projects, supported in part by USFWS African Elephant Conservation Fund since 2009, have made valuable contributions to elephant conservation. Acoustic surveys have been found to estimate elephant numbers as accurately as the standard method of counting piles of elephant dung along straight lines known as transects; they also sample a larger area making them more cost-effective. By measuring the patterns of gunshots in the forest, Wrege and team can help better inform anti-poaching efforts and measure their effectiveness. The recording devices have also helped show other disturbances in the forest, including the arrival of industrial activity and construction: In response to the noise associated with seismic exploration by oil companies, elephants appeared to shift their activities more to the night. The recordings showed a lower likelihood of calling during the day and an increase in the likelihood of calling after dark. By knowing which activities are detrimental to elephants, we can recommend better standard practices for extractive industries.

In collaboration with Dr. Andrea Turkalo, a pioneering forest elephant biologist and USFWS grantee, Wrege employed thermal imaging to further investigate elephants’ nocturnal activities over a three-year period in Dzanga Bai, in the Central African Republic.

“The thermal work was an eye-opener, visually compelling. It confirmed what we suspected we were hearing,” Wrege says. Analysis of thousands of hours of recordings from several bais showed that the composition of vocalization types was different during the night than during the day. “Something was going on at night – different behaviors or a different mix of ages and sexes – but the acoustics alone couldn’t tell us.”

Thermal imaging proved to be a valuable complement to the acoustic information. It enabled Wrege to count individual elephants, estimate sex ratio, record the structure of family groups and link specific behaviors to specific vocalizations. Even more exciting, Wrege could observe the social interactions even on the darkest of nights.

The thermal imaging helped Wrege reveal that bais may be mating hotspots for forest elephants, emphasizing the importance of these sites for elephant conservation. “Elephants’ sexual behavior was an order of magnitude higher after dark,” he says. The number of mature bulls did not increase as it got dark, but many more females and their families began entering the bai after dusk, increasing until midnight. “Maybe there were just more possible mating opportunities with more females around – or perhaps sex under the cover of darkness reduces interference by other bulls.”

Protecting bais is essential to the survival of forest elephants. Wrege is passing his knowledge on and training local biologists in the use of acoustic and other equipment to study forest elephants. As part of this training initiative, Wrege has recently created video tutorials in French and English for analyzing sound data.

Toussaint Ogombet is one of Wrege’s latest mentees. Ogombet has in turn been sharing his skills with a logging company in Gabon to oversee its wildlife management efforts. The company is supporting his use of acoustics to monitor wildlife as part of its obligations for Forest Stewardship Council (FSC) certification. Two other logging companies active in the area have since expressed interest in using acoustics to monitor and protect wildlife on the land they manage.

Wrege’s tenacious and innovative application of technology to conserve elephants persists: He is now establishing a monitoring network to follow elephant activities in an 8,000 square kilometer area in northern Republic of the Congo, including training a dedicated team of four Congolese researchers. As part of this effort he is refining an automated elephant call detector that will expedite the analysis of sound files in situ, and developing a real-time gunshot detection system to reinforce anti-poaching efforts. These efforts will help wildlife managers get information more quickly about changes in elephants’ movements and the threats they face – facilitating more rapid and strategic anti-poaching patrols.

Who goes there?

Now’s your chance to find out.

Winter is a great time to find signs of wildlife on national wildlife refuges. You can learn surprising things by studying animal tracks and imprints in the snow.

Snow prints may reveal clues to an animal’s size, diet, gait and habits. Some prints tell stories of struggle and survival.

If you’re hunting, reading animal tracks can mean the difference between finding your quarry and leaving empty-handed. If you’re simply enjoying nature, interpreting snow tracks can be a source of wonder and fun.

Salmon SuperHwy Project Improves Habitat for Fish, Infrastructure for People

   Stillwell Creek before and after

There’s a highway along the Oregon coast that you won’t find on a map. It’s one of the most used highways, with travelers crowding 10 wide at times. It’s the Salmon SuperHighway, a strategic, comprehensive effort across a six-river landscape to reconnect fish populations with the habitat they need by updating road crossings and other barriers, while also addressing flooding and road damage. When complete, it’ll span 178 river miles reconnect a 940-square-mile landscape on the North Oregon Coast that feeds Tillamook and Nestucca bays.

No Poppin’ these Collars, Key Deer

Ken Warren updates us on the New World screwworm situation at National Key Deer Refuge in Florida.

Thirty adult female Key deer have new collars, and there’ll be no “poppin’” these radio collars. 

Over a three-day period that started January 16, specially trained Key deer researchers from Texas A&M University and veterinarians and biologists from the U.S. Fish and Wildlife Service captured and placed electronic tracking collars on Key deer at Big Pine and No Name keys. These are small, lightweight flexible vinyl collars, specially made for Key deer.

These collars allow the Service to more easily find, and in turn, closely monitor these Key deer does now, and more importantly, during the upcoming fawning season for possible screwworm infestation.  Fawning season, which usually starts in March or April each year, will be a critical timeframe because of how these parasites lay eggs in open wounds, which hatch and become flesh-eating maggots. Does and fawns are particularly vulnerable during the birthing process.

Using the radio telemetry gear, Service biologists are checking on these collared does several times a week.  When fawning season begins, Service biologists will increase observations to a daily schedule. 

“We’ve got to be especially vigilant with fawning season coming,” says Dan Clark, refuge manager at Florida Keys National Wildlife Refuges Complex. “Should fertile screwworm flies be detected or an infested animal confirmed, Key deer does and fawns will be at higher risk.  If it happens, we’ll be prepared to move swiftly with preventative treatments and/or other contingency operations already planned and established to protect the subspecies.” 

As an added precaution against the parasite, the deer that have received advanced veterinary care have a number shaved onto their sides for relocation and monitoring. The Service has been visually monitoring these deer as they are observed, and will continue to do so through the next few months as a sort of welfare check. 

While significant strides have been made toward eliminating fertile screwworm flies from the environment, complete eradication remains elusive.  On January 13, two Key deer from Big and Little Munson islands, respectively, were confirmed to have been infested with screwworm by the National Veterinary Services Laboratory.  One of these was dead when it was found, and the other was euthanized on January 7 for its own welfare.

The radio collars will also provide data to improve the Service’s ability to estimate the population and identify changes in population numbers during the incident. 

The presence of New World screwworm was confirmed on National Key Deer Refuge on September 30. Since then, we have worked with the U.S. Department of Agriculture, Florida Department of Agriculture and Consumer Services, Monroe County, Florida, and others to eradicate this parasite and protect the endangered Key deer and other wildlife from infestation.

 

For the Birds: People Turn out to Celebrate Centennial of Migratory Bird Treaty

In 2016, the Service and partners celebrated all over the country the centennial of the most important document to aid in the protection of migratory birds in North America. The Convention between the United States and Great Britain (for Canada) for the Protection of Migratory Birds – also called the Migratory Bird Treaty – was signed August 16, 1916, codifying the United States’ and Canada’s commitment to protecting our shared bird resources. In 1918, the United States signed the Migratory Bird Treaty Act, the domestic legislation that formally implements the United States' commitment to the 1916 treaty. This treaty and three subsequent international conventions, with Mexico (1936), Japan (1972) and Russia (1976) provide for the protection of migratory birds that travel among and inhabit these nations.
