Topic: Marking Common Toads
Hi David I have commonly used superglue in reef aquariums to attach corals to rocks etc with no adverse effects. How long does the superglue mark stay on for and is it sloughed off when the toad shed skin? |

Topic: 25% albino spawn
Normally if the eggs are white it means that they are infertile. i have seen a LOT of infertile spawn this year and i blame it on the hot days and then freezing nights!!! Think that the males and females get ready to spawn but when the temp drops either the male cant perform :( or the sperm may be killed by the cold??? Either way, there is a lot of dead spawn up here this year. However, if it is albinos then that is interesting, i have never seen more than 2 or 3 albinos ever let along 25% of a spawn! |

Topic: 25% albino spawn
Very interesting... any chance of some pics??? Another problem this year that i encountered was that the top layer of spawn was getting trapped in the ice and embryos were getting killed in this way... i made a big effort to put a lot of the spawn into deeper water so the ice couldnt get to it... it is taking ages to develop as its not getting the heat from the sun but at least it is developing |

Topic: Early Toad Movements
Has anyone else noted regional variations of iris colour on toads? Gemma's bottom picture looks really red and some of the sites i have are like this but on other ponds the toads have a striking yellow iris... |

Topic: Horned Frog calls
Hi All, a shot in the dark... Does anyone have or know of an internet site to get a .wav file or MP3 of Ceratophyrs horned frogs calling? I am trying to encourage Budgett Frogs (Lepidobatrachus) to breed and Horned/Pacman/ceratophrys frogs are about as close to the call as I am likely to get... got a pic of the pair as they came out of aestivation here for anyone who is interested... http://photos.groups.yahoo.com/group/xfrogs/vwp?.dir=/Colins+pics/Budgetts&.src=gr&.dnm=just+woke+up.jpg&.view=t&.done=http%3a//photos.groups.yahoo.com/group/xfrogs/lst%3f%26.dir=/Colins%2bpics/Budgetts%26.src=gr%26.view=t you will need a YahhoGroups password and membership to see it though :( |

Topic: Hartland dust bowl
I'd be chasing this up quicksmart with the local wildlife liason officer with the police for a start! This area is a crime scene and should be looked at as soon as possible by a specialist and acted on, all to often people are getting away with wildlife crimes like this. What is it? 5 grand per animal killed that is under the protection of the 1981 act?

Quite often the local BBC websites have video clips of their news stories for download on real player or media player... worth checking when the story breaks... lets hope it brings attention to a group of animals often overlooked by the general population. |

Topic: Recording Program???
Is there a similar program for the PC out there that is used for recording amphibians and reptiles like what the Butterfly conservation people use for their transects? Just wondering how people store/present their data??? Cheers |

Topic: Herpetology Jobs

Topic: Tobago
Hi Alan I have done a lot of work (11 trips) to T&T. Most of it was done on Trinidad but I did spend some time on Tobago. From experience I have seen Leptotyphlops boot lace snakes killed on sight by locals who thought they were venemous and also Amphisbaena legless lizards. On both ocassions I had local help in examining leaf cutting ants nests and these animals were found and chopped by machetes before i had a chance to even speak!!! In Trinidad you often see be-headed Lachesis and Bothrops snakes at the side of the road. I once tried to stop a guy from killing a fer de lance and i almost got the machete through my neck (not quite that bad but...) so they do feel very strongly about getting rid of the venemous ones. Its not just the snakes though! Polychrus lizards are thought to be venemous and they call them the 24 hour lizard... it bites you, holds on for 24 hrs then you die. You will actually find that many locals are scared of the frogs too, including marine toads and Hyla boans Once you get to tobago you have to get a day or two in trinidad, its chalk and cheese... the internal flights can cost as little as ú30 return... before going make sure you get Murphy's book! It is very accurate and covers both islands well... here it is on Amazon... http://www.amazon.co.uk/exec/obidos/ASIN/089464971X/ref=sr_aps_books_1_1/202-6918106-2560636 Hope this helps you out...

Topic: Tobago
LOL no problem Yes, there are still some very beatifull parts to Tobago, and i beleive even parts of primary rainforest right in the middle of the island but if you go there make sure you dont have your cameras and binocculars etc on full view unless you are in a group or have made friends with some locals... In Trinidad especially there are groups of 'bandits' to watch out for... i was usually caked in swamp mud so didnt look like one of the rich american bird watchers... be prepared for some strange looks and even a few laughs at your expense if you tell people what you are looking to see :) Most are there for the bird life. Also, worth getting a license to go and look at the turtle nests, dont know where the wildlife authority is on tobago??? The most commonly seen lizards are geckos like the Thecadactylus and Gonatodes which are stunning wee things but Amievas can be seen basking themselves and watch out for some with names painted on them!!!! Local kids catch them and paint names on them! You probably wont see Iguana unless you are really lucky. Same with any snakes unless you are actively out looking for them. Commonest amphibians will be Bufo marinus and Hyla boans. But you may get to see/hear Physalaemus and Leptodactylus in puddles after rain or driving into the forest at night are lots of little Eleutherodactylus that seem to be everywhere. Ever see the BBC Bristol's Weird Nature series? A lot of the frog work was done by myself in Trinidad like the Pipa pipa and also did some work with Peripatis velvet worms Just ask if you need more info, as i said, didnt spend nearly as much time in tobago but its all relevent Cheers C |

Topic: Tobago
Alan, basically, my job was to find a list of beasties for the crew to film and to bring some back for the studio. (under licence). This included Peripatis, Pipa, some glow beetles and a few other odds and sods... The Pipa frogs actually spawned here and the whole hatching out of the back sequence got filmed too! I beleive the animals went to London Zoo after filming. None of the animals are CITES listed. Sorry for all the sci names but many dont have common ones :) here is a cool site of pics of Trini frogs... http://uk.geocities.com/craspedopus/frogs_on_line/trinfrogs.html http://uk.geocities.com/craspedopus/frogs_on_line/tobagofrogs.html |

Topic: Marking Common Toads
Hi david, I had a look at the Herpetological workers manual for you and there isnt any mention of short term marking and i believe that toe clipping would require a licence? But that aside, would it be possible to use a digital camera to take dorsal pics of them? Their markings would hopefully tell them apart, although its more commonly used for newts ventral surfaces...
