Whooping Cranes in the Central Flyway

On December 6, 2017, U.S. Army Corps of Engineers (USACE) hosted a webinar with the topic being “Whooping Cranes in the Central Flyway — Relevance for Military and Civil Works Projects During Migratory Stopover” Aaron Pearse (USGS) and Wade Harrell (USFWS) were the guest speakers.

The presentation covered recent USGS and USFWS research on Whooping Cranes, the current status of the migratory population in the Central Flyway, and about opportunities civil and military land managers have to support whooping crane habitat in the central flyway.

After some discussion and a few questions and answers, Friends Of The Wild Whoopers’s (FOTWW) President, Chester McConnell, discussed the work that FOTWW has done and continues to do on military installations and U.S Army Corps of Engineers lakes.

The entire webinar, including a Power Point presentation was recorded and can be viewed below. To hear Chester’s talk, you can listen to it beginning at the 1:02:20 mark.

Corps of Engineers Lakes Being Examined As Whooping Crane Stopover Habitat

By Pam Bates, Friends of the Wild Whoopers

Many have asked us how the Friends of the Wild Whoopers’, (FOTWW) “stopover habitat” program is doing. We can say that since we started our program that it has been met with overwhelming interest and many positive accolades. What we are happy to see is that the military, reservations and Corps of Engineers are very enthusiastic and eager to provide suitable and healthy habit for our wild whooping cranes as they migrate along the Central Flyway.

FOTWW is hard at work with the U.S. Army Corps of Engineers to protect and improve Corps’ lakes for Whooping Cranes “stopover habitat”. During their 2,500-mile migration from Canada to Texas the Whooping Cranes must stop and rest 15 to 20 times. Unfortunately this important habitat is being lost due to developments of various kinds. So FOTWW sought the Corps help. The Corps has over 100 large lakes in the migration corridor that wild Whooping Cranes use two times each year. So the Corps agreed to help and a Memorandum of Understanding has been developed between them and FOTWW.

Whooping Cranes have completed their fall migration from Wood Buffalo nesting area to Aransas Wildlife Refuge on the Texas coast. They normally stopover an average of about 10 to 20 times during their journey. They need to rest and feed occasionally during the 2,500 mile trip. Some of these birds stopover on Corps’ lakes and FOTWW believed many more will use the lakes once more habitats have been improved.

Corps lakes as potential stopover habitat

Chester McConnell, President of Friends of the Wild Whoopers’ is currently traveling to Corps lakes and making evaluations of their potential as stopover habitat. To date, he has visited Benbrook Lake, Lavon Lake Bardwell Lake and Granger Lakes in Texas. In Nebraska, he visited Harlan County Lake. And in Kansas he recently completed visits to Wilson Lake, Kanopolis Lake and Milford Lake. McConnell explained that he was pleasantly surprised at the currently excellent quality of some lake properties. And, he followed, “I believe that much more habitat can be greatly improved at very low costs.” FOTWW is committed to continue their cooperative project with the Corps to provide more habitat for the endangered Whoopers.

Stopover habitats already evaluated

FOTWW has already completed evaluations of Whooping Crane habitats on 31 U.S. military bases and 8 Indian Reservations. All had some good habitats but many needed improvements. FOTWW prepared evaluation reports with recommendations for improvements where needed.

Some of the wetland pond habitats on military bases and Indian Reservations will require minor management to suit the needs of Whoopers but the managers are up to the task advised McConnell. Military bases are legally required to have natural resources programs and the stopover project is completely compatible with the laws. Project leaders do not request base officials to do anything that would interfere with the military mission of the bases.

“Stopover places are just as important as wintering and nesting areas because Whooping Cranes can’t fly the entire 2,500 migration corridor in one trip,” McConnell explained.

Wintering Whooping Crane Update, April 7, 2017


Wintering Whooping Crane Update
Wade Harrell, – U.S. Whooping Crane Recovery Coordinator

Whooping crane spring migration is in full swing. It has been another tremendous winter season here at Aransas NWR, but the whooping cranes are ready to get back up to Wood Buffalo National Park for another breeding season.

As of yesterday, of 7 birds that have active satellite transmitters, 5 have departed Aransas NWR. Quivira NWR (Kansas) and surrounding areas seem to be a hotspot for stopovers this spring, with a group of 14 whooping cranes reported last week and a group of 8 reported this week as well as sightings of smaller groups. There have also been a number of whooping cranes reported in the Platte River in Nebraska and a number that have already made it to the Dakotas. Here in Texas, 2 marked whoopers were spotted on Ft. Hood Army Base this past week. The number of whooping cranes at Aransas will quickly dwindle over the next couple weeks. Spring migration is typically shorter in duration than fall migration, usually only taking about 30 days.

As soon as results from the Annual Whooping Crane Winter Abundance Survey are complete, we will post a summary on the Aransas NWR website.

Whooping Cranes on the Refuge

Cranes have recently been seen from the observation tower on the Refuge, but it’s difficult to say how much longer they will remain. But there are many other interesting wildlife species to view at the Refuge now, including many spring migrating songbirds, so don’t hesitate to come out and enjoy other spring wildlife watching opportunities.

Texas Whooper Watch

Please report any whooping cranes you observe in migration in Texas to Texas Whooper Watch. We’ve had a number of people making use of the new Texas Whooper Watch I-Naturalist phone app as well, which is encouraging. The old saying “a photo is worth a thousand words” applies to reporting whooping cranes as well. Just be careful not to disturb or get too close the birds!

Habitat Management on the Refuge

Refuge staff burned 4 Units this winter, totaling 4,871 acres. This year’s winter season was challenging given that our cold weather windows with consistent north winds were limited and the latter part of the winter brought significant rains.

Precipitation/Salinity

The Refuge received 6.16” of rain from January-March 2017. Freshwater levels and food resources remained high throughout most of this winter season.  Salinity levels in San Antonio Bay stayed in the low teens (ppt) most of the winter, but recent rains in the middle portion of the Guadalupe river watershed have dropped salinities significantly this last week. Let’s hope we stay in a wet cycle for a bit longer.

Cows helping Whooping Cranes

by Chester McConnell, FOTWW

Friends of the Wild Whoopers is continuing its project to encourage development and management of stopover habitats for migrating Whooping Cranes. We have visited military bases, Indian Reservations and some private lands within the six state migration corridor (TX, OK, KS, NE, SD and ND). Our mission is to provide advice to land managers about how to develop and/or manage existing ponds/wetlands to be useful as roosting/feeding sites for migrating Whooping Cranes. The cranes must stopover approximately 15 to 20 times during their 2,500 mile migration between Canada’s Wood Buffalo nesting area and their wintering area at Aransas Refuge on the Texas coast.

Some management relationships discovered

During our field trips to the various sites we have learned about some management relationships that we had not been aware of. We learned that livestock, including cattle and bison can make some ponds/wetlands more suitable as stopover areas. Livestock normally walk around ponds until they reach a shallow area where they can safely enter the ponds and drink. As they are moving around they are also grazing and trampling vegetation on pond shores. Whooping Cranes use these same shallow areas with sparse vegetation to enter the ponds to roost. We observed this relationship on numerous ponds/wetlands especially in North and South Dakota.

Whooping Cranes avoid certain sites

Whooping Cranes do not use ponds/wetlands as stopover sites where tall, dense vegetation closely surrounds the pond shore. They avoid sites anywhere they would have to move through dense vegetation where predators may be lurking such as shown in Figure 1.

Whooping Cranes
Figure 1. This pond’s shore area is covered with a dense growth of cattail vegetation. Whooping Cranes will not attempt to use ponds with these conditions. When selecting a pond where they can roost for the night, the cranes glide in (Fig. 2) and land on the shore. Then they walk into a shallow area of the pond and roost where they are safer from predators. Predators such as coyotes and bobcats can hide in dense vegetation and jump on Whoopers and kill them.

Because of their long legs and 5 foot height, they can defend themselves against predators while roosting in water. Whoopers landng by Diane Nunley

Fortunately, around some ponds, livestock have grazed and trampled the vegetation while getting a drink and grazing the more succulent vegetation (Figure 3).This results in more unobstructed shore areas that allow Whooping Cranes to use ponds as stopover sites.

Some concern has been expressed that livestock cause shoreline erosion and contamination of the stock dams/ponds that results in some murky, dirty water. While this may have some merit, FOTWW did not detect any serious problems. We carefully observed the water in the ponds visited and could clearly see the pond bottom in shallow areas. We also firmly believe that the advantages of the stock dams/ponds far outweigh any disadvantages. Use of the ponds/wetland water resources by numerous species and many thousands of individual wild animals has caused the military and Indian Reservation’s habitats to be much more productive.

Some ponds in excellent condition

Some of the stock dams/ponds on the areas visited are currently in excellent condition to serve as secure Whooping Crane stopover habitats. And some other ponds/wetlands could easily and inexpensively be developed into good habitats. However others are not useful for Whooping Cranes because cattails, bushes and trees are thick along the shore areas. On these latter ponds FOTWW recommends that they be managed for other wildlife species that prefer dense vegetative cover.

Importantly, FOTWW contends that it is not necessary or desirable to modify or manage all ponds for Whooping Cranes but rather focus on a subset with the best ponds and surrounding landscape characteristics. Open landscapes including pasture and crop land allows Whooping Cranes to easily locate the ponds and provides ready observation of any predator threats.

Note that vegetation around portions of the shore is short (A) while cattail (sp.) invasion has been restricted (B) due to livestock grazing. The shallow area (C) within the pond would provide roosting sites for Whooping Cranes.
