👀 A rare visitor has been spotted on Lisvane Reservoir!
The Grey Phalarope is a small wader that breeds in the Arctic. Its feathers change with the seasons - and this bird is wearing its winter plumage.
Phalaropes swim with a distinctive spinning motion, creating small vortices of water that are thought to bring small invertebrates to the surface where they can pick them off the surface with their short delicate bill.

👀 Mae ymwelydd prin wedi ymddangos ar Gronfa Ddŵr Llys-faen!
Aderyn hirgoes bach sy’n bridio yn yr Arctig yw’r Pibydd Llydandroed Llwyd. Mae ei blu yn newid gyda’r tymhorau – ac mae’r aderyn yma’n gwisgo’i blu gaeaf.
Mae’r Pibydd Llydandroed yn nofio mewn ffordd unigryw. Mae’n chwyrlïo’r dŵr gan greu fortecsau bach yn y dŵr sy’n denu creaduriaid di-asgwrn-cefn bach i’r wyneb er mwyn i’r aderyn eu codi’n hawdd gyda’i big fer main.
