The nightingale often sings in two three-hour sessions at night, the first ending at around midnight and the second beginning early in the morning. In late summer, the bird adds berries to this intake. It hops about in search of ants and beetles. If there are none, it eats caterpillars, spiders and earthworms. The nightingale may drop on prey from low branches, or pick it from the bark of its perching tree.
On rare occasions, it takes winged insects, such as moths and small butterflies, from the air; Autumn brings a wealth of new feeding opportunities, and the nightingale seeks out wild cherries, elderberries, sloes and currants. Open season Chicks thrive on summer insects. The nightingale selects a new partner each year, often returning to a previous site.
The male returns from his overwintering grounds before the female to establish a territory. He attracts potential mates by singing and then displays at close range. After mating, the female builds a cup-shaped nest of dead leaves and coarse grass. She incubates the eggs alone, but both parents feed the nestlings during the two weeks of rapid growth between their hatching and leaving the nest.
The voice of a male nightingale is celebrated as one of the most beautiful of the bird kingdom. His song varies by season and circumstances. It is richest, loudest and most often performed in late spring, when the male sings at night to attract a mate and to proclaim territory. The song is also very loud. Ornithologist Tim Birkhead recalls being kept awake all night by a nearby nightingale; at 90 decibels, he could feel its song resonating in his chest.
Changes in farming, the structure of the countryside here and in their wintering grounds in West Africa, hazards on migration journeys and other factors mean that the range of nightingales in Britain is shrinking rapidly. This secret valley, guarded, fenced off from the outside world, with its empty roads through ghost streets, scrubby woodland, open grass and scattered ponds, is ideal for nightingales. Its many and varied habitats provide stages for singers, concealment for nests and a complex of edges between them for foraging ants, beetles and other ground-living invertebrates that feed the youngsters.
Countless generations of nightingales were born here before the MoD and not only survived but also ironically thrived in years of soldiers preparing for war in distant lands. Now the army has evacuated, a home-grown conflict lays siege to Lodge Hill. Despite holding the highest breeding population of nightingales in the country, Lodge Hill was earmarked by Medway council for development: 5, new houses. The enquiry was abandoned after the plans were withdrawn in September , but new plans for a scaled-down 2,home development were submitted in march Destroying it would set a very dangerous precedent.
We hope that councillors come to appreciate that having the best place for nightingales in the country is exactly that — something for Medway to be proud of. They prefer habitats with coppiced tree species, and are most often found in hazel trees.
This is ideal for Luscinia megarhynchos because it provides a good hiding place from predators while allowing them to search for food and make nests safely. Due to the recent decline in the population of common nightingales in England, researchers have investigated whether a cutback of suitable habitats may have caused the decline.
Various factors, including climate change, changes in the quality of habitats, the introduction of Reeve's muntjacs Muntiacus reevesi , and the re-introduction of roe deer Capreolus capreolus have all contributed to population declines in Britain. Reeve's muntjacs and roe deer graze in the woods typically inhabited by common nightingales, which reduces the density of shrubs.
Hewson, et al. Common nightingales are rather plain in appearance compared to their remarkable singing abilities. They are slightly larger than European robins Erithacus rubecula and their body is brown in color except on the underside, where the feathers become lighter. They have broad, chestnut colored tails, and large, black eyes which are adorned with a white ring around each eye.
Males and females are similar in appearance, except that males tend to be slightly larger, with larger wingspans. However, females sometimes weigh more because males have higher metabolic rates due to their tendency to sing. One of the most notable characteristics of common nightingales is their beautiful singing ability, especially by male birds.
Common nightingales are well known for singing during the night, hence their name. Older males have improved mating success due to their larger song repertoire and territory, which attracts females better. Researchers have not discovered yet why song repertoire increases so dramatically in older males. Upon mating successfully, males change the types of their songs by reducing their whistle songs, which are used to attract females, and ceasing their nocturnal songs until their mate lays eggs.
Kiefer, et al. The mating season is a highly competitive time for common nightingales. It takes a tremendous amount of energy to sing and male songs may reflect their body condition, resulting in female selection of the best singers Schmidt et al. More aggressively singing males will have a better chance of mating success.
Males defend their nest territory very aggressively, fighting and chasing away trespassing birds. Common nightingales are seasonally monogamous. Breeding in common nightingales takes place around mid-May each year.
Nests are usually set up by the female among the twigs found in dense shrubs, using dried leaves and grass. Incubation lasts approximately thirteen to fourteen days by the female.
Each egg is 21 by 16 mm, weighing 2. Common nightingales reach sexual maturity at the age of one. Before the eggs hatch, the female incubates the eggs, and both parents project the eggs from predators. When the eggs hatch, both parents take care of the offspring by feeding and nurturing them until they can survive on their own.
The fledgling period lasts between 11 to 13 days. Robinson, Common nightingale typical lifespan ranges from one to five years. The oldest recorded age is at 8 years and 4 months old.
Although little is known about what typically limits the lifespan of common nightingales, there is no doubt that predation and habitat reduction contribute to the relatively short lifespan.
There has been no recorded lifespan of a nightingale in captivity. Common nightingales are solitary outside of the breeding season. They migrate to the African tropics in the winter.
Common nightingales are territorial, but there are no social hierarchies. Males become even more territorial during mating season, when they engage in song contests to attract females. Common nightingale songs can be divided into two categories, whistle songs and non-whistle songs.
Whistle songs are distinct and used most often in territorial defense and mate attraction Kiefer et al. Males respond aggressively to other males who may be entering their territory. Not much is known about common nightingale behavior because they are small and prefer to hide in thick scrubs.
Unless migrating, they fly only short distances, from branch to branch. It is more common for people to hear them than see them.
Home range sizes are not known in common nightingales. Common nightingales communicate with others by singing whistle and non-whistle songs. Whistle songs are used during breeding season. The number of whistle songs decrease when males successfully mate. Males lose weight each night when they sing Thomas,
