Modrwywyd cywion Glaslyn 2024 ar y nyth ar Orffennaf 2 gan y modrwywr BTO profiadol Jimmi Hill am yr ail flwyddyn yn olynol.
Mae pwysau’r ddau gyw hynaf yn awgrymu eu bod yn fenywaidd a’r ieuengaf o’r nythaid yn wryw. Diolch unwaith eto i'r tîm modrwyo ymroddedig am wneud gwaith gwych.
***********
The 2024 Glaslyn chicks were ringed on the nest on July 2 by experienced BTO ringer Jimmi Hill for the second year running.
The weight of the two oldest chicks suggests that they are females and the youngest of the brood is a male. Thank you once again to the dedicated ringing team for doing a wonderful job.
