For instance, in a 2011 study, Rico-Guevera and Rubega used high-speed photography to shed light on the process by which hummingbirds obtain nectar. The two researchers refuted an 1833 theory that claimed hummingbirds used capillary action to capture nectar; instead, they use the split tip of their tongue and the fringe-like lamellae.
Even though there is a lot of research on bird tongues, there are still many species for which little is known about the function of the tongueor even the beakin the process of obtaining and consuming food. A portion of the issue stems from the challenge of examining the tongue of living birds. Some of these questions are being answered by new techniques like high-speed photography, but there are still many obstacles to overcome.
For instance, pigeons have 27 to 59 taste buds, parrots have 300 to 400, and chickens have about 24. Additionally, birds’ taste buds are positioned differently than ours. They are mostly located on the roof or floor of the mouth and at the base of the tongue in birds. Because the anterior (front) portion of the tongue is usually hard and horny, it is thought that they are not present there. Birds are thought to be able to taste lipids (fats), sweet, salt, brine, bitter, and concentrations of sugar. Dunlins and Sanderlings detect where worms have been burrowing in the sand by using their taste buds.
Nancy Johnston, a retired computer scientist, developed an interest in photography and birding eight years ago after seeing her first Burrowing Owl at Berkeley’s Cesar Chavez Park. As a participant in the 2014 Master Birder program, which was jointly sponsored by the California Academy of Sciences and the Golden Gate Bird Alliance, Nancy conducted research on bird tongues. The complete paper she wrote on the subject is available at Avian Tongues, along with additional illustrations. Our next Master Birder class will start in February 2015.

The tongues of birds that remove food particles from mud and water appear to be the most intricate. Their tongues contain papillae, which are hair-like or barb-like structures that come in a variety of sizes and forms and aid in removing food particles. The actions of various ducks and flamingos are two excellent examples of this behavior. We are aware of how flamingos remove food particles from mud and water by sweeping their bills back and forth while keeping their heads tipped back. Certain ducks, like the Mallard, Northern Shoveler, and Cinnamon Teal (Figure 5), will occasionally filter feed and use their tongue as a pump. They let mud and water into their mouths when they bury their tongue. The solid food particles are then captured when they press their tongue against the palate, causing the water or mud to be ejected sideways between the papillae. In addition to filter feeding, geese also use their powerful tongue and bill to tear off plant stems and clip vegetation near the ground.
“I was curious to see if it was true that parrots live more than 100 years?” Jack Madsen of Good Thunder wrote. “Apparently, as the song says, ‘It ain’t necessarily so.” The kakapo is a nocturnal, flightless New Zealand parrot that inhabits the slow lane. Its average lifespan is 58 years, but it can reach nearly 90 years. Macaws can live 60 years in the wild. Winston Churchill supposedly owned Charlie, who lived to be over 100 years old. It was allegedly claimed that the bird had been trained to spew derogatory remarks about Hitler and the Nazis. Although it’s a compelling tale, experts have questioned Charlie’s veracity, claiming that Churchill never owned a parrot like that. Lady Soames, the daughter of Winston Churchill, denied that her father had ever owned a macaw. Churchill sold Polly, his African grey parrot, before taking office as prime minister, according to Soames. It is known that parrots kept in captivity can live up to 80 years. The world’s oldest parrot, Cookie the Cockatoo, passed away at the Brookfield Zoo at the age of 83.
Foster Otten of Hayward asked if all birds have tongues. Although their tongues are not as fleshy as ours, birds nevertheless have tongues. Different birds have different types of tongues. The tongues of birds that consume nectar are designed like tubes to effectively extract liquids. In order to help them catch insects, certain woodpeckers have long, barbed tongues. One could argue that a bird’s tongue functions more as a food finder than a taster.
Everything is nearly copacetic. I think we just missed another storm of the century. It veered a little east of the meteorologists predictions. It went to New Jersey instead of Minnesota. I had to build a new bookshelf in my den. All of the books dropped to the floor when the previous one broke. I have only my shelf to blame. I prepared some roasted garlic as a thank you for a job well done. A handful of the strongest onions I could find were added. It was delectable. It wasn’t until it had crept up on me that I could even see my breath. I went to the cities for a family gathering. I was reminded of our 50 beautiful states and the fact that many people in them do not wish to spend the winter there by looking at all the license plates on the vehicles traveling on the interstate. That morning, I took a while to get on the road. I slid back three steps for every step I took forward on the icy walk to my garage. I had to give up and try to walk back to the house in order to reach my truck. .
A squirrel ran up a tree and positioned itself between me and the trunk. A squirrel knows where the back of a tree is. Two Greek words, skia, which means “shadow,” and oura, which means “tail,” are the origin of the word squirrel. A squirrel can cover its body with its tail to shield itself from the sun, rain, or snow. Its also a warm blanket when sleeping.
