Physical characteristics
Large and colorful bird, being iridescent blue, black and chestnut. Roller without tail streamers, proportionately larger headed than most congeners, and in flight appears long-necked. Nominate race with head, neck amd underparts light blue, whitish around base of bill, and short, thin blackish eyestripe. Rufous brown upperparts, with back, rump and tail-coverts ultramarine blue. Wing coverts greenish-blue, marginal ones purple, primary coverts and bases of primaries azure-blue, remiges otherwise black. Tail greenish-blue with darker base, central feathers greyish. Race semenowi slightly paler than nominate.
Habitat
Warm and sunny lowlands, in open countryside with patches pine or oak woods with heathery clearings, orchards, mixed farmland, broad river valleys, and dissected plains with scattered thorny or leafy trees.
Other details
Coracias garrulus is a widespread summer visitor to southern and eastern Europe, which constitutes >50% of its global breeding range. Its European breeding population is relatively small (30%) overall.
This bird is breeding in north-western Africa, south and eastern Europe and western Asia, reaching Pakistan and Mongolia in the east. It winters in sub-Saharan Africa. The population of the European Union has undergone a strong decrease in numbers and a contraction of its distribution since the end of last century. Currently it is estimated at 5000-12000 breeding pairs. Since 1991 it has become extinct in Germany. The principal reasons of this decline are habitat degradation, agricultural intensification and increasing use of pesticides. In some countries the species is also persecuted
Feeding
Diet mainly invertebrates: beetles and other hard-bodied insects, and some small vertebrates. Exceptionally, fruits such as grapes and figs eaten. Many live scorpions taken, and species may be and accomplished scorpion predator. Several other prey items are distasteful: stink-grasshoppers and carabid, lampyrid and silphid beetles. Forages mostly from elevated perch, watching ground intently.
Conservation
Coracias garrulus occurs as two subspecies: the nominate breeds from Morocco, southwest and south-central Europe and Asia Minor east through northwest Iran to southwest Siberia (Russia); and semenowi, which breeds in Iraq and Iran (except northwest) east to Kashmir and north to Turkmenistan, south Kazakhstan and northwest China (west Sinkiang). The species overwinters in two distinct regions of Africa, from Senegal east to Cameroon and from Ethiopia west to Congo and south to South Africa. It has a large global population, including an estimated 100,000-220,000 individuals in Europe (50-74% of the global breeding range). However, following a moderate decline during 1970-1990, the species has contined to decline by up to 25% across Europe during 1990-2000 (including in key populations in Turkey and European Russia). Overall European declines exceeded 30% in three generations (15 years). Populations in northern Europe have undergone severe declines (Estonia: 50-100 pairs in 1998 to no known breeding pairs in 2004, Latvia: several thousand to under 30 pairs in 2004, Lithuania: 1,000-2,000 pairs in 1970s to 20 pairs in 2004), and in Russia it has now disappeared from the northern part of its range. However, there is no evidence of any declines in Central Asia. Should these populations be shown to be declining, the species may warrant uplisting further to Vulnerable. Threats include persecution on migration in some Mediterranean countries and hundreds, perhaps thousands, are shot for food in Oman every spring. Use of pesticides reduces food availability, and the species is sensitive to changing farming and forestry practices. [conservation status from birdlife.org]
Breeding
Monogamous, solitary and territorial, with typical rolling and diving aerial display. Nest site an unlined cavity in a large tree, building, cliff or riverbank. 4-5 eggs, incubation by female, 17-19 days. Chick hatches naked and blind, has closed spiny feather sheaths by 13th day
Migration
An intercontinental migrant, almost entire world population wintering in Africa South of Sahara. In autumn has occurred in great abundance in Algeria and Morocco, though only small numbers winter in West Africa; strong passage up Nile Valley and on West coast of Red Sea, also across Ethiopia, and in October-December through East Africa, especially Rift Valley; weak passage through Arabia. Winters mainly in East & South West Africa in Kenya, Tanzania, North East Botswana and East Namibia; present in October-April/May in South Africa, where prone to flock, evidently still moving South in November-December, and seen in South West Cape Province only in December-February. Congregates in East Tanzania from late March, and in early April up to hundreds of thousands travel in North in narrow corridor along East coastal lowlands to North East Somalia, in one of continent's most spectacularly visible migrations, with thousands passing over a given locality in a few hours, e.g. 40,000-50,000 at Balad, Somalia, on single day in April. In Somalia, migrants fly 300-500 m above land, evenly spaced in column several Km wide, at ground speed of c. 48km/h; also common to abundant in Ethiopia in April. From Somalia birds emigrate at Cape Gardafui, with flocks seen from light aircraft arriving on Dhofar plain in South Oman, after sea crossing of 600 km, and many then cross a further 600 km of desert to reach Persian Gulf; singletons and loose flocks of 10-30 birds frequent in Oman from Mid-April to mid-May, often flying by day on broad front North or North East, or North West on Batinah coast. Recoveries of ringed birds suggest that they travel the 10,000 km from East Europe to Central Africa at c. 67 km/day, and return in spring 110 km/day.

Holy Roller
You've been down too long in the midnight sea
Oh what's becoming of me
Ride the tiger
You can see his stripes but you know he's clean
Oh don't you see what I mean
Gotta get away
Holy Roller
Shiny diamonds
Like the eyes of a cat in the black and blue
Something is coming for you
Race for the morning
You can hide in the sun 'till you see the light
Oh we will pray it's all right
Gotta get away-get away
Between the velvet lies
There's a truth that's hard as steel
The vision never dies
Life's a never ending wheel
Holy Roller
You're the star of the masquerade
No need to look so afraid
Jump on the tiger
You can feel his heart but you know he's mean
Some light can never be seen
Sorry for butchering the lyrics to "Holy Diver"
LOL

The Indian Roller (Coracias benghalensis), also called the Blue Jay in former times is a member of the roller family of birds. They are found mainly in the Indian Subcontinent, but also in a wider arc stretching from Iraq to Thailand and are best known for the aerobatic displays of the male during the breeding season. They are very commonly seen perched along roadside trees and wires and are commonly seen in open grassland and scrub forest habitats. It is not migratory, but undertakes some seasonal movements. Several states in India have chosen it as their symbol.
