Gull Excitement at Hagerman NWR

Text and photos by Laurie Sheppard

In early spring, Hagerman National Wildlife Refuge attracts large numbers of gulls, as many preparing for migration join those that wintered here. Most are Ring-billed Gulls, but it’s worthwhile to look closely through the large flocks because frequently you will find a few Herring Gulls, Franklin’s Gulls, or other species migrating through. This week, though, we have had a very unusual visitor – a Glaucous Gull (Larus hyperboreus) has landed in our midst. Jack Chiles reports that this is the first time one has been seen at Hagerman NWR and many birders have rushed to the refuge to get that rare sighting.

Glaucous Gulls are very large, with some approaching 28 inches, compared to the Ring-billed Gulls’ mere 17-21 inches. The Glaucous Gulls’ typical wingspan is nearly five feet, which rivals that of the familiar Turkey Vulture, and the gulls can exhibit bursts of speed of up to 40 mph. They are said to be the second largest gull species, behind only the east coast’s Great Black-backed Gull. They are strikingly pale and have been described as “ghostly”. Adult Glaucous Gulls have a yellow bill and both adults and juveniles have dark pink legs and feet. In any group of gulls, the refuge’s visitor will appear much bigger and lighter than others nearby, particularly because of its white wing tips. Most other gull species found in north Texas have dark wing tips.

Note the differences in size and coloring between the larger Glaucous Gull and the smaller, more common Ring-billed Gull.
Glaucous Gulls breed in the Arctic, along marine and freshwater coasts, or on nearby tundra, cliffs, or ice edges. Both sexes build their nest which is little more than a shallow depression in a mound of grass, moss, twigs, and occasionally feathers with little or no lining. These might be at the water’s edge or in grassy areas atop cliffs, on the cliff’s ledges, or in the rocky scree at the base of the cliff. Both parents tend the eggs and care for the young until they become independent. It takes four years for a Glaucous Gull to fully reach maturity and their lifespan in the wild may be ten years or more.

Glaucous Gull shows its pale feathers and pink feet as it prepares to land.
 Like most gulls, Glaucous Gulls are omnivores with a varied diet. They will eat fish, berries, mollusks, small birds or mammals, eggs and chicks of other birds, and vegetation. They will also scavenge dead fish, carrion, and human refuse, and will attempt to steal food from other gulls and terns. They often forage while walking or swimming. The gull at the refuge has frequently been seen in the vicinity of other gulls, especially in the shallow water near Harris Creek or the exposed area off J Pad.

During the winter, Glaucous Gulls migrate south along the coastal edges of the continent, but most adults remain north of Virginia in the east and California in the west. Occasionally, some birds migrate further south, but nearly all of those are immature Glaucous Gulls. This appears to be the case with the one seen on the refuge, which has the black-tipped bill and occasional brown freckling of a third winter bird. Migrating Glaucous Gulls are rarely found very far inland, which makes our visitor unusual.

Markings of an immature gull include the black-tipped pink bill bordered by brown feathers and slight brown freckling on the chest and wings.

Midwinter Bald Eagle Survey

By Jean Flick  
                                             
On a cold day in January, a group of hearty individuals, led by Paul Balkenbush, Hagerman National Wildlife Refuge Deputy Manager, searched the Texas side of Lake Texoma for the presence of bald eagles.  HNWR has supported the Midwinter Bald Eagle Survey for a number of years, providing bald eagle counts that are used to estimate trends of wintering bald eagle populations across the lower 48 states.



Each January, several hundred individuals count eagles along standard, non-overlapping survey routes as part of this nationwide survey.  Started in 1979, counts were first coordinated by the National Wildlife Federation and are now coordinated by the U.S. Army Corps of Engineers (USACE). 

Paul Balkenbush coordinates this effort for the Texas portion of Lake Texoma.  The 2018 survey was completed in one day in January, by individuals who were each assigned portions of the shoreline area between Highway 69/75 and I-35.  Team members may travel by boat or vehicle to search for eagles, with most choosing to travel by vehicle.  This year, the team completed 859 minutes of survey time with 67.3 miles of shoreline observed.  Bald eagle sightings included 4 adult and 8 immature eagles.

Paul reports the team’s data, including the time spent and miles observed.  This data, including the number of eagles/shoreline mile and number of eagles/survey hour is compiled from regions across the country and can then be used to support bald eagle relative density estimates.

The USACE website provides summary trend tables from 1986-2010, which show an overall increasing trend in eagle sightings in the majority of national regions (6 of 9 regions) but an overall decreasing trend in sightings in Texas during that same time period.  A wide range of variables may impact this data.

The USFWS considers the recovery of bald and golden eagles to be a conservation success story.  When the bald eagle was adopted as our national symbol in 1782, the country may have had as many as 100,000 nesting eagles.  By 1963, with only 487 nesting pairs of bald eagles remaining, the species was in danger of extinction. Loss of habitat, shooting, and DDT poisoning contributed to the near demise of our national symbol.

The Endangered Species Act was enacted in 1973, and in 1978 the bald eagle was listed as endangered throughout much of the contiguous U.S.  Habitat protection afforded by the Endangered Species Act, the federal government’s banning of DDT, and conservation actions taken by the American public have helped bald eagles make a remarkable recovery.  Bald eagles were removed from the endangered species list in August 2007 because their populations recovered sufficiently.  (USFWS Endangered Species website and Fact Sheets)

Data from a variety of sources, including estimates from the annual Midwinter Survey, contribute to our body of knowledge regarding the continued successful recovery of bald eagle populations.  Paul is always looking for members to join the Bald Eagle Survey team.  Participation is open to any interested birder who wants to spend a day looking for eagles along the lakeshore.  Contact Paul at the refuge office if you would like to participate on the team in January 2019.

Smartweed February Plant of the Month at Hagerman NWR

Yellow-headed Blackbird, Pennsylvania Smartweed at HNWR, by Philip Jones
Smartweed is a plant that is native to the lower 48 states and Alaska in the U.S. as well as in much of Canada.  When Hagerman National Wildlife Refuge was first established, smartweed seed was among the 10 - 15 tons of seeds of various plants sent by the Fish and Wildlife Service to both Hagerman and Tishomingo national wildlife refuges, to be planted at both refuges along the edges of newly built Lake Texoma (Denison Herald, February 18, 1945).  Since February is the anniversary month for the establishment of the Refuge, we chose Smartweed as the featured plant this month.

According to the Lady Bird Johnson Wildflower Center, smartweed is in the buckwheat family and is important to waterfowl and other birds, which use it for food and cover. 

At least 50 species of birds have been observed feeding on the seeds, including ducks, geese, rails, bobwhites, mourning dove, and ring-necked pheasant. The seeds and other parts are eaten by mammals such as the white-footed mouse, muskrat, raccoon, and fox squirrel. (Wikipedia)


Great Egret in Field of Smartweed at HNWR, by Kim Morris
The Wildflower Center notes that about 75 species of smartweeds occur in North America.  Pink blooming Polygonum pensylvanicumand white blooming smartweed, Polygonum lapathifolium,
can be found on the Refuge. We know this because thanks to the birds, we also have volunteer plants of both species in the Butterfly Garden each summer.

Pennsylvania, or pink, smartweed, is mainly  identified by spikes of numerous flowers and encircling leaf sheaths.  The white blooming smartweed is also known as Curlytop knotweed, and Pale Smartweed.  Pale Smartweed (P. lapathifolium), is closely related to Pink Smartweed and has white or pale rose, arching flower spikes and usually smooth stems. Both are found in gardens as well as in damp waste places and wetlands.   The plant is annual, so watch for it to come back from seed this spring. The bloom-time is March-May.

Listen to the Mockingbird

Northern Mockingbird at Hagerman NWR, Photo by Bill Hurst
"If you’ve been hearing an endless string of 10 or 15 different birds singing outside your house, you might have a Northern Mockingbird in your yard. These slender-bodied gray birds apparently pour all their color into their personalities. They sing almost endlessly, even sometimes at night...(Cornell, All About Birds)

Noting that the mockingbird "... is found in all parts of the State, in winter and in summer, in the city and in the country, on the prairie and in the woods and hills ... is a singer of distinctive type, a fighter for the protection of his home, falling, if need be, in its defense, like any true Texan ...", the Texas legislature designated the mockingbird (Mimus polyglottos) as official state bird in 1927.  The northern mockingbird is also the state bird of Florida, Arkansas, Tennessee, and Mississippi.

In the novel, To Kill a Mockingbird, where the mockingbird symbolizes innocence and goodness, Miss Maudie says

"Mockingbirds don't do one thing but make music for us to enjoy.  They don't eat up people's garden, they don't nest in corncribs, they don't do one thing but sing their hearts out for us. that's why it's a sin to kill a Mockingbird.

In Carl Sandburg's poem, Wilderness, we find this verse:

"There is an eagle in me and a mockingbird … and the eagle flies among the Rocky Mountains of my dreams and fights among the Sierra crags of what I want … and the mockingbird warbles in the early forenoon before the dew is gone, warbles in the underbrush of my Chattanoogas of hope, gushes over the blue Ozark foothills of my wishes—And I got the eagle and the mockingbird from the wilderness.


"Hush, little Baby, don't say a word,
Mama's gonna buy you a Mockingbird.

And if that mockingbird don't sing,
Mama's gonna buy you a diamond ring.

Northern Mockingbirds have extraordinary vocal abilities; they can sing hundreds of songs, including the songs of other birds, insect and amphibian sounds, even an occasional mechanical noise.  You can check out the "music" on this video from Cornell.

Cornell gives these Cool Facts about the mockers' singing:

  • It’s not just other mockingbirds that appreciate a good song. In the nineteenth century, people kept so many mockingbirds as cage birds that the birds nearly vanished from parts of the East Coast. People took nestlings out of nests or trapped adults and sold them in cities such as Philadelphia, St. Louis, and New York, where, in 1828, extraordinary singers could fetch as much as $50.
  • Northern Mockingbirds continue to add new sounds to their repertoires throughout their lives. A male may learn around 200 songs throughout its life.
  • Northern Mockingbirds sing all through the day, and often into the night. Most nocturnal singers are unmated males, which sing more than mated males during the day, too. Nighttime singing is more common during the full moon.
  • Northern Mockingbirds typically sing from February through August, and again from September to early November. A male may have two distinct repertoires of songs: one for spring and another for fall.
  • The female Northern Mockingbird sings too, although usually more quietly than the male does. She rarely sings in the summer, and usually only when the male is away from the territory. She sings more in the fall, perhaps to establish a winter territory.
So listen up!  Do you hear the mockingbird?

American Kestrel



Photo by Nature's Realm
According to Cornell's  All About Birds, the American Kestrel is North America's smallest falcon and the most colorful raptor.  

Hunting for insects and other small prey in open territory, kestrels perch on wires or poles, or hover facing into the wind, flapping and adjusting their long tails to stay in place. 

Photo by Jack Chiles

Recently, photographers have been posting a number of photos of this beautiful little raptor taken at Hagerman National Wildlife Refuge on the Friends of Hagerman Facebook Page.  So we had the kestrel in mind as our topic for the week - then we discovered that a North Texas writer, Renny Gehman has the cover article, on the kestrel,  in the February, 2018 issue of Bird Watcher's Digest.  Don't miss her five-page article, with excellent descriptors.

As Gehman points out, kestrels nest in cavities, relying on existing holes.  They have one or two broods a season, with 4 - 5 eggs.  According to Cornell, which offers box plans, kestrels take readily to nesting boxes, but you would be fortunate to have a nesting pair in our North Texas area, as they are seldom seen here in summer, per the Hagerman Bird Census.

January Plant of the Month - Possumhaw

(https://aggie-horticulture.tamu.edu/newsletters/hortupdate/2009/nov09/Possumh.html)

Have you seen this bright berried deciduous tree or shrub that just stands out in the winter landscape? It is Ilex decidua  - commonly known by a number of names - Possumhaw, Possumhaw holly, Deciduous holly, Meadow holly, Prairie holly, Swamp holly, Welk holly, Deciduous yaupon, Bearberry, Winterberry.

Possumhaw in the rain at HNWR, by Dana Crites
According to the Ladybird Johnson Wildflower Center website,

"Opossums, raccoons, other mammals, songbirds, and gamebirds eat the fruit of this and related species."

The spring blooms of the possumhaw also provide nectar for insects and the horizontal branches offer a platform for birds' nests.


From the Texas Native Plants Database

"Possumhaw is a large shrub or small tree frequently encountered in or near seasonally wet areas in Central and East Texas. Fairly nondescript in summer, female plants with their red, orange, or yellow fruit can become a blaze of color in the fall and winter landscape. It is the widest ranging of all Texas hollies and can adapt to a wide range of soil conditions. It can be grown in shade, but it fruits best in partial shade to full sun. Females need a male pollinator for good fruit set.


Possumhaw growing in Visitor Center landscape at HNWR
The Ladybird site notes that possumhaws can grow to 36' in height, while TAMU says 10' -12', occasionally 20', and 6' - 10' in width.  It is native within a "box" formed along the East Coast from  Virginia to Florida, from Virginia to westward to Kansas and down to Texas and in the states in between.

Watch for possumhaw this winter as you walk the trails at Hagerman National Wildlife Refuge.
