'''Spoonbills''' are a group of large, long-legged wading [[bird]]s in the family [[Threskiornithidae]], which also includes the [[Ibis]]es. |

|||
'''Spoonbills''' are a genus, '''''Platalea''''', of large, long-legged wading [[bird]]s. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name ''Platalea'' derives from [[Ancient Greek]] and means "broad", referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera. |
|||
:''"Spoonbill" could also mean [[Northern Shoveler]] or [[Paddlefish]]''. |
|||
All |
All spoonbills have large, flat, spatulate bills and feed by wading through shallow water, sweeping the partly opened bill from side to side. The moment any small aquatic creature touches the inside of the bill—an [[insect]], [[crustacean]], or tiny [[fish]]—it is snapped shut. Spoonbills generally prefer fresh water to salt but are found in both environments. They need to feed many hours each day. |
||
==Taxonomy== |
|||
Spoonbills are monogamous, but, so far as is known, only for one season at a time. Most species nest in [[tree]]s or reed-beds, often with ibises or [[heron]]s. The male gathers nesting material—mostly sticks and reeds, sometimes taken from an old nest—the female weaves it into a large, shallow bowl or platform which varies in its shape and structural integrity according to species. |
|||
The [[genus]] ''Platalea'' was introduced in 1758 by the Swedish naturalist [[Carl Linnaeus]] in 1758 in the [[10th edition of Systema Naturae|tenth edition]] of his ''[[Systema Naturae]]''.<ref>{{cite book | last=Linnaeus | first=Carl | author-link=Carl Linnaeus | year=1758 | title= Systema Naturae per regna tria naturae, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis | volume=1 | edition=10th | page=139 | publisher=Laurentii Salvii | location=Holmiae (Stockholm) | language=Latin | url=https://www.biodiversitylibrary.org/page/727044 }}</ref> The genus name is [[Latin]] for "spoonbill" and is derived from the [[Ancient Greek]] ''platea'' meaning "broad", referring to the distinctive shape of the bill.<ref>{{cite book | last= Jobling | first= James A | year= 2010| title= The Helm Dictionary of Scientific Bird Names | url= https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling | publisher=Christopher Helm | location = London | isbn = 978-1-4081-2501-4 | page=[https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling/page/n309 309]}}</ref> The [[type species]] was designated as the [[Eurasian spoonbill]] (''Platalea leucorodia'') by [[George Robert Gray]] in 1840.<ref>{{ cite book | last=Gray | first=George Robert | author-link=George Robert Gray | year=1840 | title=A List of the Genera of Birds : with an Indication of the Typical Species of Each Genus | location=London | publisher=R. and J.E.

They have traditionally been thought to form one of two subfamilies, '''Plataleinae''', in the family [[Threskiornithidae]], which also includes the [[ibis]]es (Threskiornithinae). Molecular studies, including a 2013 study, have suggested instead that they form a clade within the family with several cosmopolitan ibis genera, separate from another clade of New World ibises.<ref name="Ramirez">{{cite journal|last1=Ramirez|first1=J.L.|last2=Miyaki|first2=C.Y.|last3=Del Lama|first3=S.N.|title=Molecular phylogeny of Threskiornithidae (Aves: Pelecaniformes) based on nuclear and mitochondrial DNA|journal=Genetics and Molecular Research|date=2013|volume=12|issue=3|pages=2740–2750|doi=10.4238/2013.July.30.11|url=http://www.funpecrp.com.br/gmr/year2013/vol12-3/pdf/gmr2779.pdf|pmid=23979898|doi-access=free}}</ref> |

The female lays a clutch of about 3 smooth, oval, white [[egg (biology)|eggs]] and both parents incubate; chicks hatch one at a time rather than all together.

|||
A 2010 study of [[mitochondrial DNA]] of the spoonbills by Chesser and colleagues found that the roseate and yellow-billed spoonbills were each other's closest relative, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus ''Platalea'' or alternatively for two of the species to be placed in monotypic genera named as ''Platibis'' and ''Ajaja''. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.<ref>{{cite journal|author1=Chesser, R.Terry |author2=Yeung, Carol K.L. |author3=Yao, Cheng-Te |author4=Tians, Xiu-Hua |author5=Li Shou-Hsien |year=2010|title=Molecular phylogeny of the spoonbills (Aves: Threskiornithidae) based on mitochondrial DNA|journal=Zootaxa|volume=2603 |issue= 2603|pages=53–60|doi=10.11646/zootaxa.2603.1.2 |issn=1175-5326}}</ref> |

==Description== |
|||
Spoonbills are most easily distinguished from ibises in the shape of their bill, which is long and flat and wider at the end. The nostrils are located near the base of the bill so that the bird can breathe while the bill is submerged in water. The eyes are positioned to provide spoonbills with binocular vision, although, when foraging, tactile senses are important too. Like ibises, spoonbills have bare patches of skin around the bill and eyes.<ref name="hbw">{{cite journal |last1=Matheu|first1=E.|last2=del Hoyo|first2=J.|editor1-last=del Hoyo |editor1-first=Josep |editor2-last=Elliott |editor2-first=Andrew |editor3-last=Sargatal |editor3-first=Jordi |editor4-last=Christie |editor4-first=David A. |editor5-last=de Juana |editor5-first=Eduardo |year=2020 |title=Ibises, Spoonbills (''Threskiornithidae'') |journal=Handbook of the Birds of the World Alive |url=https://www.hbw.com/family/ibises-spoonbills-threskiornithidae |publisher=Lynx Edicions |location=Barcelona, Spain |doi=10.2173/bow.thresk1.01|s2cid=216218320|access-date=5 December 2017 |url-access=subscription }}</ref> |

The six [[species]] of spoonbill in two [[genus|genera]] are distributed over much of the world. |
|||
Spoonbills are [[Monogamy in animals|monogamous]], but, so far as is known, only for one season at a time. Most species nest in [[tree]]s or [[reed bed]]s, often with ibises or [[heron]]s. The male gathers nesting material—mostly sticks and reeds, sometimes taken from an old nest—the female weaves it into a large, shallow bowl or platform which varies in its shape and structural integrity according to species. |
|||
* '''[[Eurasian Spoonbill]]''' (''Platalea leucorodia''): This is the most widespread species, which occurs in the northeast of [[Africa]] and much of [[Europe]] and [[Asia]] across to [[Japan]]. Adults and juveniles are largely white with black outer wing-tips and dark bills and legs. Breeds in reed-beds, usually without other species. |
|||
* '''[[Black-faced Spoonbill]]''' (''Platalea minor''): Found in [[Taiwan]], [[China]], [[Korea]] and [[Japan]]. |
|||
The female lays a clutch of about three smooth, oval, white eggs and both parents incubate; chicks hatch one at a time rather than all together. The newly hatched young are blind and cannot care for themselves immediately; both parents feed them by partial [[Regurgitation (digestion)|regurgitation]]. Chicks' bills are short and straight, and only gain the characteristic spoonbill shape as they mature. Their feeding continues for a few weeks longer after the family leaves the nest.

* '''[[African Spoonbill]]''' (''Platalea alba''): Breeds in [[Africa]] and [[Madagascar]]. A large white species similar to Common Spoonbill, from which it can be distinguished by its pink face and usually paler bill. Its food includes [[insect]]s and other small creatures, and it nests in trees, marshes or rocks. |
|||
==Species and distribution== |
|||
* '''[[Royal Spoonbill]]''' (''Platalea regia''): Most common in south-east [[Australia]], but regularly found in smaller numbers on other parts of the continent when temporary wetlands form; in [[New Zealand]], particularly the [[South Island]], and sometimes as stragglers in [[New Guinea]], [[Indonesia]], and the Pacific Islands. Its food is aquatic life, and it nests in trees, marshes or reed-beds. |

Spoonbills are a genus, Platalea, of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name Platalea derives from Ancient Greek and means "broad", referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera.
All spoonbills have large, flat, spatulate bills and feed by wading through shallow water, sweeping the partly opened bill from side to side. The moment any small aquatic creature touches the inside of the bill—an insect, crustacean, or tiny fish—it is snapped shut. Spoonbills generally prefer fresh water to salt but are found in both environments. They need to feed many hours each day.
Taxonomy
[edit]The genus Platalea was introduced in 1758 by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae.[1] The genus name is Latin for "spoonbill" and is derived from the Ancient Greek platea meaning "broad", referring to the distinctive shape of the bill.[2] The type species was designated as the Eurasian spoonbill (Platalea leucorodia) by George Robert Gray in 1840.[3][4]
They have traditionally been thought to form one of two subfamilies, Plataleinae, in the family Threskiornithidae, which also includes the ibises (Threskiornithinae). Molecular studies, including a 2013 study, have suggested instead that they form a clade within the family with several cosmopolitan ibis genera, separate from another clade of New World ibises.[5]
A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the roseate and yellow-billed spoonbills were each other's closest relative, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus Platalea or alternatively for two of the species to be placed in monotypic genera named as Platibis and Ajaja. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.[6]
Description
[edit]Spoonbills are most easily distinguished from ibises in the shape of their bill, which is long and flat and wider at the end. The nostrils are located near the base of the bill so that the bird can breathe while the bill is submerged in water. The eyes are positioned to provide spoonbills with binocular vision, although, when foraging, tactile senses are important too. Like ibises, spoonbills have bare patches of skin around the bill and eyes.[7]
Breeding
[edit]Spoonbills are monogamous, but, so far as is known, only for one season at a time. Most species nest in trees or reed beds, often with ibises or herons. The male gathers nesting material—mostly sticks and reeds, sometimes taken from an old nest—the female weaves it into a large, shallow bowl or platform which varies in its shape and structural integrity according to species.
The female lays a clutch of about three smooth, oval, white eggs and both parents incubate; chicks hatch one at a time rather than all together. The newly hatched young are blind and cannot care for themselves immediately; both parents feed them by partial regurgitation. Chicks' bills are short and straight, and only gain the characteristic spoonbill shape as they mature. Their feeding continues for a few weeks longer after the family leaves the nest. The primary cause of brood failure appears not to be predation but starvation.
