When I awoke on April 19, I didn’t expect that I’d end up seeing a new state bird before the day ended. Thanks to timely notices of a new bird sighting by email, I used my work break to drive to Elizabethton, Tennessee, to see a white-faced ibis at the Carter County Rescue Squad pond. The opportunity for unexpected appearances by birds like the white-faced ibis is why I love spring migration.
Tom McNeil spotted the bird at a much larger pond on the campus of Northeast State Community College in Elizabethton. After he reported the bird, I was able to use a work break to travel to the location and find the bird nearby at the smaller pond, where several area birders had already arrived. The ibis had moved to this smaller pond after departing the larger pond where it was first detected.
This is only the second record of a white-faced ibis for Northeast Tennessee.
The white-faced ibis is a widespread wading bird, nesting from the western United States and Canada south through Mexico, as well as from southeastern Brazil and southeastern Bolivia south to central Argentina, and along the coast of central Chile.
I saw white-faced ibises for the first time during a trip to Utah in May of 2006. The state had enjoyed a spring with ample rainfall, and every flooded field and pasture contained flocks of these distinctive wading birds. These flooded fields provided temporary habitat for numerous other birds, including cinnamon teal and Wilson’s phalarope.
The white-faced ibis is almost identical in appearance to the glossy ibis, which is the most widespread ibis in the world. The glossy ibis ranges across six continents, absent only from Antarctica. In the United States, the glossy ibis ranges mostly along the southern Atlantic coastal area. I have observed this bird at several locations in South Carolina.
The similar appearances of white-faced and glossy ibis presents challenges to identification, which was the case with this recent visitor. The bird found in Elizabethton lacked the white plumage in the face that gives the species its common name. Fortunately, the bird did plainly show one physical trait — red eyes — that easily distinguishes it from the related glossy ibis. Sometimes, all it takes to clinch an identification is a simple physical characteristic such as, in this case, a red eye.
A third ibis native to North America is the white ibis. The Audubon Society identifies the white ibis as one of the most numerous wading birds in Florida, but the bird is common also in other parts of the southeast with appropriate wetland habitat. Like the wood stork, the ibis has declined in Florida in recent decades largely as a result of human encroachment.
The white ibis looks like a humorously absurd bird that could have been invented by Dr. Seuss. The extravagant, all-white plumage is contrasted by pinkish-orange legs, an extremely long, downcurved, reddish-pink bill and bright blue eyes. In flight, the white ibis shows black feathers on the edges of its wings.
I’ve seen white ibises in Tennessee as well as in South Carolina and Florida. In the Sunshine State, another relative — the unmistakable scarlet ibis — is sometimes observed in the wild. The scarlet ibis inhabits tropical South America and islands of the Caribbean, but the species is often held in zoos and other attractions. Escaped birds rather than strays are often the source of sightings in Florida of this vibrant scarlet-feathered ibis.
All ibises have long, downcurved bills. These birds usually feed in small flocks, probing wetlands for prey such as crustaceans, small fish, amphibians, insects, and various invertebrates. Worldwide, there are about 34 species of ibis, including the red-naped ibis, black-faced ibis, green ibis, straw-necked ibis and African sacred ibis, which is the bird often depicted in tombs and other monuments of ancient Egypt. This ibis was associated with the Egyptian god, Thoth, who was often depicted as a man with the head of an ibis.
The brief visit from the white-faced ibis provides a good reminder that we’re in the midst of spring migration. Stay alert for those unexpected birds. You never know what you might see.
Readers continue to report hummer arrivals
A few other readers have shared their first spring hummingbird sightings.
• Bunny Medeiros of Abingdon, Virginia sent me an email to announce her first sighting. “To my delight, the day after I put out my feeder a hummer appeared,” she wrote. The bird, a male, made his appearance on April 14.
• Rhonda Eller of Chilhowie, Virginia, saw her first ruby-throated hummingbird of spring on April 18. “Surely spring is going to come and stay!” Rhonda predicted on her post on my Facebook page.
