Anifail asgwrn-cefn gydag adenydd, pig, plu, dwy goes a gwaed cynnes yw'r **aderyn** (lluosog **adar**). Mae bron pob aderyn yn gallu hedfan, mae adar dihediad yn cynnwys yr estrys, y ciwïod, y pengwiniaid, a.y.y.b. Ceir mwy na 10,400 o rywogaethau o adar. Maen nhw'n byw mewn llawer o gynefinoedd gwahanol ledled y byd. Adareg yw astudiaeth adar.

## Anatomi

O gymharu â fertebratau eraill, mae gan adar strwythur corff sy'n dangos llawer o ymaddasiadau anarferol, yn bennaf i hwyluso hedfan. Mae eu coesau blaen wedi newid i adenydd. Mae gan adar big ysgafn heb ddannedd ac mae codennau aer tu fewn i'w hesgyrn.

## Atgenhedliad

Mae adar yn dodwy wyau â phlisgyn caled. Mae'r rhan fwyaf o adar yn gwneud nyth lle maen nhw'n deor eu hwyau. Mae rhai adar yn cael eu geni'n ddall a noeth. Mae adar eraill yn gallu gofalu amdanynt eu hunain bron ar unwaith.

## Mudiad

*Prif: Aderyn mudol*
Mae llawer o rywogaethau yn mudo er mwyn dianc rhag tywydd oer. Mae miliynau o adar sy'n nythu yn Hemisffer y Gogledd yn mudo i'r de. Mae rhai adar Hemisffer y De yn mudo i'r gogledd. Mae Môr-wennol y Gogledd yn hedfan ymhellach nag unrhyw aderyn arall o'r Arctig i'r Antarctig.

## Esblygiad

Esblygodd adar o'r theropodau, h.y. deinosoriaid deudroed sawrisgiaidd cigysol o'r isurdd *Therapoda*, mae'n debyg. Yr archeopterycs yw'r adar ffosiledig henaf a fu fyw tua 150 miliwn o flynyddoedd yn ôl.

## Adar a dyn

Mae adar yn ffynhonnell bwysig o fwyd i bobl. Mae rhai adar fel yr iâr a'r twrci wedi eu ffermio ar gyfer eu cig neu wyau. Anifeiliaid anwes poblogaidd yw rhai adar e.e. y byji a'r caneri.

Mae llawer o adar wedi eu peryglu oherwydd hela a dinistr amgylcheddol. Mae elusennau fel Cymdeithas Audubon yn yr Unol Daleithiau a’r RSPB yn y DU yn ymgyrchu i amddiffyn adar.

## Mewn llenyddiaeth Gymreig

Efallai'r cyntaf i gofnodi rhai o'r adar a welodd ar ei deithiau oedd Gerallt Gymro. Nid oedd ganddo ryw lawer o ddiddordeb ynddynt ond mae rhai o'r sylwadau'n ddigon diddorol, serch hynny, e.e.

*"Clywir yn y coed cyfagos chwibaniad pereiddlais aderyn bach, y dywedodd rhai mai cnocell y coed ydoedd, ond eraill, yn fwy cywir, mai peneuryn. Cnocell y coed y gelwir yr aderyn bach, yr hwn a alwyd pic yn yr iaith Ffrangeg, a dylla'r dderwen â'i ylfin cryf ... A pheneuryn y gelwir aderyn bach hynod am ei liw euraid a melyn, a ddyry, yn ei dymor priodol, yn lle cân, chwibaniad melys; ac oddi wrth ei liw euraid y derbyniodd ei enw, peneuryn."*

Mae'n debygol iawn mai'r euryn (*golden oriole*) oedd yr aderyn a glywodd Gerallt neu, fel y tybiai ei gyfeillion, cnocell werdd.

Un o gerddi mwya'r Gymraeg ydy cywydd i'r "Alarch" gan Dafydd ap Gwilym. Ceir hefyd nifer o hen benillion sy'n sôn am adar; dyma un, er enghraifft:

Gwyn eu byd yr adar gwylltion,
Hwy gânt fynd i'r fan a fynnon',
Weithiau i'r môr ac weithiau i'r mynydd,
A dod adref yn ddigerydd.
Yn y Mabinogi fe drowyd Blodeuwedd yn dylluan am gamfihafio.
