Forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. Having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Referring to an animal that lives in trees; tree-climbing.
The days are getting longer and the temperatures warmer – what an ideal time to talk about birds. In this blog, let us explore some NLS resources that will bring you a little closer to our feathered friends. The nightingale is the official national bird of Iran. Habitat quality is a central concept in species conservation.
Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Nightingales are very secretive birds but keep a keen ear out for their distinctive song between April and June. Scrub forests develop in areas that experience dry seasons. Young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. The range contraction and fragmentation means the range size in 2008–11 was 43% smaller than in 1968–72. Nightingales mostly feed on invertebrates, grubs, and berries.
The reasons for this decline are thought to encompass the degradation and loss of the scrubby woodland habitat upon which Nightingales depend to breed, including by browsing deer. The nightingale’s song is most often heard during spring and early summer. The female builds a cup-shaped nest out of dry leaves, twigs, and grass. She lays four to six eggs, which hatch in about two weeks. Tracking and ringing studies have taught us that Nightingales winter in the humid zone of West Africa, and arrive back in the UK to breed in April. Males sing at night until paired up, after which time their famous song is limited to dusk and dawn.
Early writers assumed the female sang when it is in fact the male. The song is loud, with an impressive range of whistles, trills and gurgles. Its song is particularly noticeable at night because few other birds are singing. This is why its name includes “night” in several languages. Only unpaired males sing regularly at night, and nocturnal song probably serves to attract a mate. Singing at dawn, during the hour before sunrise, is assumed to be important in defending the bird’s territory.
They have a pale ring around their eye, and paler grey neck. Their tail is longish and when perched often appears raised. Juveniles look quite like juvenile robins as they are mottled brown in colouration but are much larger in size.
In this madrigal, words get repeated in a way that clearly evokes the chatter of birds. Nightingales are predominantly brown with a few slight grey areas, a white-grey throat pale underparts with a grey tinge to them. Their wings and tail are light brown in colouration with no distinct markings. Nightingales arrive in the UK to breed in spring and leave to warmer climes in late summer. Nightingales have been celebrated in poetry for their song.
These three counties, together with Hampshire, held the highest densities, whereas counties at the range edge are increasingly characterised by a small number of sites of relatively high population Doeat.top Animal diet density. Such sites become increasingly isolated as birds disappear from surrounding countryside. Contrary to popular opinion, Nightingale is not the only bird that sings at night.
Woodland-scrub mosaics appear to be important breeding habitats for Nightingales (Holt et al. 2012c). A management advice sheet has been produced by the BTO and gives full details about the precise management requirements for Nightingales. The common nightingale is slightly larger than the European robin, at 15–16.5 cm (5.9–6.5 in) length.
Males respond aggressively to other males who may be entering their territory. Common nightingales are so named because they frequently sing at night as well as during the day. The name has been used for more than 1,000 years, being highly recognisable even in its Old English form nihtegale, which means “night songstress”.
They are normally seen eating within deep cover of hedges or shrubs, foraging on the ground. Nightingales are not really seen using feeders, but if you do use one, make sure it is a ground feeder.

In 1606 Renaissance composer John Bartlett found fame when he published his Booke of Ayres with a Triplicitie of Musicke. Number 10 is entitled “Of all the birds that I do know,” a metaphorical poem by George Gascoigne (1542?-1577).
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., 2006).
Reproduction in which eggs are released by the female; development of offspring occurs outside the mother’s body. Offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).
In fact, due to its recent decline, you are more likely to hear other birds singing after dark. This video illustrates the difference in song between the four most common ‘Night Singers’ – Robin, Blackbird, Song Thrush and of course, Nightingale. Nightingales construct their nests close to the ground, often surrounded by leaf litter, dense cover, and shrubbery. Females build the nest from dead leaves and grass in a cup shape, which is then lined with fur or fine grasses prior to laying. Clutches are normally laid between May and June, with 1-2 broods laid annually.
