Hen Turkeys Protecting Poults

6-12-17 wild turkey hen 197

Wild Turkey chicks, or poults, can be seen these days scurrying at their mother’s feet, trying to keep up with her as they forage in fields for grasshoppers and other insects. How the hen turkey reacts to a human (or other) threat depends on the age of her poults. If they are very young (under a week old), she huddles stock still with her brood in a frozen position.   With wings and tail spread, she provides them with shelter. If they are detected, she gives a vocal command to her young to remain “frozen,” and feigns an attack on the intruder, simultaneously making a “putting” sound to quiet her chicks. By the time they are a week old, poults tend to evade possible predators by running away. At nine days old and later, most poults fly into low vegetation when threatened. By the time her brood is three weeks old, the hen commands them to fly into trees at the sign of danger.

Tom Turkeys Gobbling & Strutting

3-30-17 tom turkey IMG_7637In the Northeast, male Wild Turkeys began gobbling and strutting in late February. Their courtship ritual usually starts before females are receptive, and continues into late March and early April, when mating typically takes place. Hearing a tom turkey gobble is as sure a sign of spring as the sight of one strutting.

At this time of year males are bedecked with blue wattles (flap of skin on throat) and snoods (fleshy piece of skin that hangs over beak), and bright red major carbunkles (bulbous, fleshy growths at the bottom of the turkey’s throat). Displaying these adornments while slowly gliding around a female, the male fans his tail, lowers his wings with the primaries dragging on the ground/snow, elevates the feathers on his back and throws his head backward the female. If she is receptive, she lowers herself and crouches on the ground, signaling to the male that he may mount her. (Thanks to Chiho Kaneko for photo op.)

Wild Turkey Hens On Eggs

This is what a typical Wild Turkey’s nest looks like – anywhere from 4 to 17 eggs in a shallow depression in the ground.  Sometimes, however, turkeys engage in a practice referred to as “egg dumping.” A hen turkey comes along and lays a few eggs in several other turkeys’ nests, in an effort to maximize the number of her offspring that will survive.  Up to 26 eggs have been found in a single Wild Turkey nest.  The hen turkey that built the nest doesn’t reject the additional eggs, but rather, welcomes them to her brood, incubates them and treats them as her own.  All of the precocial chicks are out of the nest within 24 hours of hatching and follow the hen, who feeds them for a few days until they learn to find food on their own.

Wild Turkeys Flying

wild turkey 186Wild Turkeys spend 99.9% of their time on the ground, and often it is assumed they cannot fly. While the Wild Turkey is one of the heaviest North American birds, second only to the Trumpeter Swan, it definitely is able to lift itself off the ground and take flight. In fact, a Wild Turkey is amazingly well adapted for explosive, short-distance flight, perfect for escaping predators.

When startled or threatened, a turkey squats slightly, takes a few steps and then explodes upward with help from its powerful legs. Turkey wings are highly cupped, which enables quick takeoff, and the breast muscles that power a turkey’s wings are built for rapid but brief exertions. After take-off, which can be at a steep or small angle, a turkey’s wings beat rapidly until the desired height is attained. The turkey usually then glides to a tree or the ground, where it lands.

Although the maximum distance turkeys can fly in a single flight is estimated to be approximately one mile, they rarely fly more than about 100 yards, which is usually enough to bring it to safety. The average speed a turkey obtains while flying any distance is anywhere between thirty and fifty-five miles per hour. Equally as (or more) impressive than its ability to fly is a turkey’s ability to swim. They have been observed tucking their wings in close, spreading their tail and kicking while in the water.

Wild Turkeys’ Struggle for Food Begins

wild turkey in snow121Wild Turkeys do not migrate. During the winter they often separate into three distinct groups — adult males (toms), young males (jakes) and females (hens) of all ages — and spend their days seeking out plant (90 percent of diet) and animal (10 percent of diet) matter. In the summer, greens and insects make up much of their diet; in the winter, Wild Turkeys rely heavily on acorns, beechnuts, crabapples and hawthorn fruit, as well as agricultural grains such as corn, buckwheat, soybeans and oats.

The winter survival of Wild Turkeys depends much more on snow conditions that impact the procuring of food than on the temperature. While research has shown that turkeys can tolerate very cold temperatures, they need adequate food to keep from losing significant body weight and eventually starving to death. In parts of northern New England, the current Nor’easter has dumped a large amount of deep, loose fluffy snow, which turkeys can’t walk on or dig through in order to reach nutritious nuts. For this reason, turkeys frequently seek out agricultural fields that are windblown and provide relatively easy access to grains.

Wattles, Caruncles & Snoods

11-27-14  HAPPY THANKSGIVING IMG_7637Wild tom turkeys have a number of ways of impressing hens in addition to displays involving their feathers. Among them are wattles, caruncles and snoods — fleshy protuberances that adorn their throats and beaks. A large wattle, or dewlap, is a flap of skin on the throat of a male turkey. The bulbous, fleshy growths at the bottom of the turkey’s throat are major caruncles. Large wattles and caruncles have been shown to correlate with high testosterone levels, good nutrition and the ability to evade predators, which makes the genes of a tom turkey with them very desirable to a female. The snood, another fleshy outgrowth which hangs down over the male’s beak, is normally pale and not very long. When he starts strutting and courting a hen, the snood (and caruncles) becomes engorged with blood, making it redder and longer. This impresses both male and female turkeys –the males avoid or defer to him and the females’ interest in him is heightened. A longer snood has also been correlated with a lack of internal parasites, making toms with large snoods even more irresistible to hens.

Wild Turkeys Mating

3-25-13 -wild turkeys mating P1040933The most prominent courtship behavior of male wild turkeys (toms) consists of two displays: gobbling and strutting. Both begin in late February in northern New England, before the females (hens) are receptive, but by late March the males begin to reap the fruits of their labor. The gobbling of the males attracts females or competing males over considerable distances. The tom turkey begins to “strut” only after a hen appears. While strutting, he fans his tail, lowers his wings with the primaries dragging on the ground/snow, elevates the feathers on his back and throws his head backward as he appears to glide around a female. If she is receptive, she assumes a “sexual crouch” on the ground, signaling to the male that he may mount her. (Thanks to Chiho Kaneko for this photograph.)
