Creuyrfa diddorol Interesting Heronry


Mae gan Len natur fyddin o wirfoddolwyr sydd yn darllen a chofnodi data diddorol o hen ddyddiaduron
Mae'r dyddiaduron yn dod o sawl man ac mae llawer o ddata diddorol a pwysig yn cael ei gasglu.

Mae un cofnod diweddar yn dod o ddyddiadur ddi enw o Abergele rhwng 1922 - 1944, ac yn nodi cofnod o Greyrfa ym Modedern, Ynys Môn yn 1925. Meddai’r dyddiadur  “ to Holyhead, visited Heronry at Treiorwerth, Bodedern, about a dozen nests, apparently eggs but failed to climb up. Other nests looked half finished”

Mae'r cofnod yma yn gynt na chofnodion sydd wedi casglu gan arolwg nythod Crëyr, ac felly dyma yrru’r cofnod I John Marchant sydd yn rheoli arolwg  Crëyr. Dyma John yn ôl hefo mwy o wybodaeth ddiddorol.
“Max Nicholson's paper from the 1928 survey lists this and Cadnant as the only heronries known to be active in Anglesey at that time.  The notes (British Birds 22: 291) say "+ 8 before 1907, 20 c1907, 10 in 1927". In 1928 there were subgroups of 4 and 2 nests: the first site was founded in 1876 and the second c1918, probably from Plas Tregaion (sic).  The reference cited is:

Forrest, H.E. (1919) Handbook to the Vertebrate Fauna of North Wales”

Mae'r data yma yn rhedeg o 1876 tan heddiw, sydd gennych gofnod i guro hyn?

Llen natur has an army of volunteers who are examining and extracting data from Historical diaries. These diaries come from various sources and a lot of interesting and valuable data is being collected.

A recent record comes from a nameless diary from the Aberegele area for the years 1922  - 1944 and records a heronry at Boderern Anglesey in 1925. To quote the diary for 3rd March “ to Holyhead, visited Heronry at Treiorwerth, Bodedern, about a dozen nests, apparently eggs but failed to climb up. Other nests looked half finished”

This record precedes the existing Heronries survey so I submitted the record to John Marchant who organises the Heronries census, who came back with even more interesting information.
“Max Nicholson's paper from the 1928 survey lists this and Cadnant as the only heronries known to be active in Anglesey at that time.  The notes (British Birds 22: 291) say "+ 8 before 1907, 20 c1907, 10 in 1927". In 1928 there were subgroups of 4 and 2 nests: the first site was founded in 1876 and the second c1918, probably from Plas Tregaion (sic).  The reference cited is:

Forrest, H.E. (1919) Handbook to the Vertebrate Fauna of North Wales”

So this data set runs from 1876 to the present, can you beat that ?

Arolwg Crecod yng Nghymru Wales Chat Survey

Yn ystod 2012 mae BTO Cymru yn cynnal arolwg ar aelodau o deulu’r Crecod. Arolwg Adar sy’n Magu yw'r ffordd hanfodol o gofnodi a thracio newidiadau yn niferoedd y rhywogaethau yma. Ond mae rhaid cael arolwg mwy canolbwyntiedig i weld beth yw eisiau cynefinoedd y rhywogaethau yma. Mae'r arolwg yn cael ei chynnal o Ebrill I Fehefin a fydd yn cofnodi Clochdar y cerrig, Crec yr eithin a’r Tinwen y garn. Am fwy o fanylion yr arolwg neu i gofrestru a gofyn am sgwâr ewch i gwefan y BTO.



BTO Cymru are undertaking a survey of breeding Chats in 2012. BBS is the recognised method for producing trends in these species, but for a fuller understanding of their ecology a more focused survey is required to ascertain their habitat needs. The survey will run from April to June and will be recording Stonechat, Whinchat, and Wheatear . For more details of the survey or to register and request a square go to the BTO web site.
