Cough it up, Sunday 28th October 2018

-
I've often commented that you don't have to see a creature to know that it's been around, all animals will leave a clue to their presence, this is no better illustrated than in birds which produce a "pellet" of the indigestible parts of their food.

 People are often surprised and often misunderstand what is going on when a bird regurgitates one of these pellets, many think that the bird is vomiting, I guess in a way they are, except of course it's essential to their wellbeing that they remove the indigestible parts of the food via their mouths rather than letting the materials pass right through their gut, think of an owl trying to pass a mouse skull, ouch!
Barn Owl
All sorts of birds produce pellets, here are just a few; Owls, Crows, Gulls, Herons, Kingfishers, Hawks, Falcons and even Penguins (not that we get many of these in Carmarthenshire).

Carrion Crow pellets
This week I watched a bird produce the bright purple pellets in the photograph, they were about the size of a garden pea, I'd be interested if anyone can identify the bird from the pellet.
What bird produced these
Dissecting owl pellets is a great way to engage children, its easy to do, (once you have the pellet) and there are plenty of great reference materials out there to help identify the bones and skulls found, it's not smelly or dirty but washing hands afterwards is a must.
Short-eared Owl pellets, 
with a bird ring from a Meadow Pipit (see a previous blog for the details)
The Field Studies Council, FSC, produce loads of great easy to use guides, including this one on Owl pellets.

A Tern of events Sunday 7th April

  Prynhawn da pawb,  I hope you have all weathered storm Kathleen. It's been a heck of a week personally,  I'm hoping this coming week will be better. Well storm Kathleen is the last weather event we need but sadly any meagre control we may have had over our climate has long run out. On a brighter note though a phone call from the county bird recorder set me off to Sandy Water Park, (SWP) where 13 Arctic Terns, 2  Little Gulls and a mixed flock of 2-300+ mostly Sand Martins and a few Swallows were playing in the wind. Little Gull If you're up to speed with the last few months then you will know that we have installed bird nesting rafts on SWP and at Ffynnon Helyg near Pwll, with a view of hopefully attracting  Common Terns to nest !!. OK its a coincidence but a nice one Earlier in the week a Little Ringed Plover was seen flying over the SWP raft, what's that saying, build and they will come! Lots of migrant birds have now arrived and we have some great places to seek th

SLOW WORM fest..

  Croseo pawb,  Another busy week which has kept me on my toes, as usual, I've dealt with fish poaching, illegal vehicle intrusion, and odd things going on with a "Badger Sett". The relevant authorities are dealing with the poaching and vehicle issues whilst I have investigated the "goings on". Nothing of concern as there is no Badger sett just an outlier burrow probably an old boar Badger or one of last years youngsters pushed out from the main sett, quite common at this time of year when the sow badgers will be giving birth. Our amazing volunteers have been out and about, today they were at Morfa Berwig LNR, where I joined them this afternoon for their first reptile survey of the year, a very productive survey with 16 refugia to check and a total of 22  Slow worms, five Grass snakes, although two were out basking away from the refugia and just one Common Lizard. One refugia had seven Slow worms in a loose ball under it an incredible sight, another had Slow w

Carmarthenshire - Did you Know?

  Well its ages since I've found time to write a blog post apologies for that but here we go with some interesting facts and personal thoughts about Carmarthenshire wildlife, and a bit further afield. Did you know: That we have a County plant, Whorled Caraway, Carum verticullatum ; found in typical Rhos pasture a feature of the Carmarthenshire landscape though often under threat from changes in agricultural practices Did you Know: That there are 311 species of birds recorded as being seen in the county, a respectable figure by an measure, amongst the rarities are Blue-winged Teal, a species from North America, Black Stork an European species which itself has a limited range. Having a decent stretch of well watched coastline the county is well placed for observers to document the seasonal arrival and departures of migrating birds such as Northern Wheatear, Swift, Willow Warbler, the Carmarthenshire Bird Club is a very welcoming bunch of like minded individuals and its well worth joi
