Variations in shape of bill used for recognition of sub-families. Despite long legs, walk rather than run and escape by flying. Five families of which three (Ardeidae, Ciconiidae, Threskiornithidae) represented in our region; others - Balaenicipitidae (Shoe-billed Stork) and Scopidae (Hammerhead) - monotypic and exclusively Ethiopian. Re lated to Phoenicopteriformes, which sometimes considered as belonging to same order, and, more distantly, to Anseriformes. Behavioural similarities suggest affinities also to Pelecaniformes (van Tets 1965; Meyerriecks 1966), but close relationship not supported by studies of egg-white proteins (Sibley & Ahlquist 1972). Suggested also, mainly on osteological and other anatomical characters, that Ardeidae should be placed in separate order from Ciconiidae and that Cathartidae (New World vultures) should be placed in same order as latter (Ligon 1967).

Ardea Cinerea (Grey Heron) Family: Ardeidae (Herons and Egrets) Order: Ciconiiformes (Storks, Herons and Ibises) Class: Aves (Birds)
UWU The Online Guide to the Animals of Trinidad and Tobago Behaviour Ardea cinerea (Grey Heron) Family: Ardeidae (Herons and Egrets) Order: Ciconiiformes (Storks, Herons and Ibises) Class: Aves (Birds) Fig. 1. Grey heron, Ardea cinerea. [http://www.google.tt/imgres?imgurl=http://www.bbc.co.uk/lancashire/content/images/2006/06/15/grey_heron, downloaded 14 November 2012] TRAITS. Grey herons are large birds that can be 90-100cm tall and an adult could weigh in at approximately 1.5 kg. They are identified by their long necks and very powerful dagger like bills (Briffett 1992). They have grey plumage with long black head plumes and their neck is white with black stripes on the front. In adults the forehead sides of the head and the centre of the crown are white. In flight the neck is folded back with the wings bowed and the flight feathers are black. Each gender looks alike except for the fact that females have shorter heads (Seng and Gardner 1997). The juvenile is greyer without black markings on the head and breast. They usually live long with a life span of 15-24 years. ECOLOGY. The grey heron is found in Europe, Asia and Africa, and has been recorded as an accidental visitor in Trinidad. Grey herons occur in many different habitat types including savannas, ponds, rivers, streams, lakes and temporary pools, coastal brackish water, wetlands, marsh and swamps. Their distribution may depend on the availability of shallow water (brackish, saline, fresh, flowing and standing) (Briffett 1992). They prefer areas with tall trees for nesting UWU The Online Guide to the Animals of Trinidad and Tobago Behaviour (arboreal rooster and nester) but if trees are unavailable, grey herons may roost in dense brush or undergrowth. -

The Grey Heron
Bird Life The Grey Heron t is quite likely that if someone points out a grey heron to you, I you will remember it the next time you see it. The grey heron is a tall bird, usually about 80cm to 1m in height and is common to inland waterways and coasts. Though the grey heron has a loud “fraank” call, it can most often be seen standing silently in shallow water with its long neck outstretched, watching the water for any sign of movement. The grey heron is usually found on its own, although some may feed close together. Their main food is fish, but they will take small mammals, insects, frogs and even young birds. Because of their habit of occasionally taking young birds, herons are not always popular and are often driven away from a feeding area by intensive mobbing. Mobbing is when smaller birds fly aggressively at their predator, in this case the heron, in order to defend their nests or their lives. Like all herons, grey herons breed in a colony called a heronry. They mostly nest in tall trees and bushes, but sometimes they nest on the ground or on ledge of rock by the sea. Nesting starts in February,when the birds perform elaborate displays and make noisy callings. They lay between 3-5 greenish-blue eggs, often stained white by the birds’ droppings. Once hatched, the young © Illustration: Audrey Murphy make continuous squawking noises as they wait to be fed by their parents. And though it doesn’t sound too pleasant, the parent Latin Name: Ardea cinerea swallows the food and brings it up again at the nest, where the Irish Name: Corr réisc young put their bills right inside their parents mouth in order to Colour: Grey back, white head and retrieve it! neck, with a black crest on head. -

Great Egret Ardea Alba
Great Egret Ardea alba Joe Kosack/PGC Photo CURRENT STATUS: In Pennsylvania, the great egret is listed state endangered and protected under the Game and Wildlife Code. Nationally, they are not listed as an endangered/threatened species. All migra- tory birds are protected under the federal Migratory Bird Treaty Act of 1918. POPULATION TREND: The Pennsylvania Game Commission counts active great egret (Ardea alba) nests in every known colony in the state every year to track changes in population size. Since 2009, only two nesting locations have been active in Pennsylvania: Kiwanis Lake, York County (fewer than 10 pairs) and the Susquehanna River’s Wade Island, Dauphin County (fewer than 200 pairs). Both sites are Penn- sylvania Audubon Important Bird Areas. Great egrets abandoned other colonies along the lower Susque- hanna River in Lancaster County in 1988 and along the Delaware River in Philadelphia County in 1991. Wade Island has been surveyed annually since 1985. The egret population there has slowly increased since 1985, with a high count of 197 nests in 2009. The 10-year average count from 2005 to 2014 was 159 nests. First listed as a state threatened species in 1990, the great egret was downgraded to endan- gered in 1999. IDENTIFYING CHARACTERISTICS: Great egrets are almost the size of a great blue heron (Ardea herodias), but white rather than gray-blue. From bill to tail tip, adults are about 40 inches long. The wingspan is 55 inches. The plumage is white, bill yellowish, and legs and feet black. Commonly confused species include cattle egret (Bubulus ibis), snowy egret (Egretta thula), and juvenile little blue herons (Egretta caerulea); however these species are smaller and do not nest regularly in the state. -
Great Blue Heron Ardea Herodias
Great Blue Heron Ardea herodias Throughout the 20th century, Great Blue Herons have been increasing within Ohio. Between 1918 and 1935, Hicks (1935) reported 61 colonies in 33 counties with an estimated statewide population of 1500–2000 pairs. Except for one heronry in Warren County, most of these colonies were confined to the northern half of glaciated Ohio and along the unglaciated plateau in eastern Ohio as far south as Tuscarawas County. However, not all of these colonies were extant at the same time and Hicks was also unaware of some newly established colonies. A large heronry near Fremont was composed of 1118 nests in 1935 (Campbell 1968), indicating that Hicks’ population estimate was probably low. Ohio’s population of Great Blue Herons increased in subse- quent decades, although this expansion was poorly documented. Only Robbins, C. S., et al. (1986) reported a significant increase in Ohio between 1965 and 1979 based on data obtained from the Breeding Bird Survey routes. The current distribution of Great Blue Heron colonies within Ohio was initially surveyed during 1980 and 1981 by the Division of Natural Areas and Preserves. The results of this preliminary survey were expanded during the Atlas Project to produce records of 89 colonies scattered across 52 counties; only these colonies are exhibited on the accompanying map. Every colony was not necessarily active each year, particularly small Mike Williams - ODNR Photographer colonies with 10 or fewer pairs. Additionally, a number of small colonies may have been overlooked. The distribution of breeding Great Blue Heron colonies may be located adjacent to lakes, Great Blue Herons has expanded along the unglaciated Allegheny rivers, and marshes, although inland heronries are frequently Plateau where they are more widely distributed than reported by found in isolated woodlots several miles from any water. -

Developing a Research Network on Glossy Ibis, a Neglected Cosmopolitan Species
Developing a research network on Glossy ibis, a neglected cosmopolitan species Álvaro Arenas Patiño © 2014 The Project in a nutshell The Glossy ibis (Plegadis falcinellus) is the only cosmopolitan species of the Threskiornithidae family (ibis and spoonbills) and among the most widely distributed bird species in the world ([1] see map at the bottom of the document). Nonetheless, no knowledge exists on the intraspecific phylogeny and very little is known about the (meta)populations dynamics. We aim to fill this gap by setting up a research network and by implementing modern analytical tools (e.g. molecular and statistical) we nowadays dispose of. Some puzzling aspects of Glossy ibis abundance and distribution Little is known about the movement ecology of this species especially when focusing on a large spatial scale. In most ornithology books the Glossy ibis is described as migratory with nomadic elements [2] with populations at tropics being more sedentary than others. However, references are rarely provided and, to the best of our knowledge, only a few data have been ever collected on the Glossy ibis dispersal behavior. According to historical records, breeding was very rare in W Europe while common in North Africa and S Spain before the 20th century when it became almost absent in all these regions [3–5]. In 1996 seven pairs settled at Doñana, a wetland area in SW Spain, from where the species begun an astonishing population increase reaching about 8,000 pairs in current times [6,7]. Since then, the Glossy ibis has started to colonize other areas in W Europe and the Mediterranean Basin from where it had been absent for decades or even had never been recorded as a breeder species.
