This spring I spent April and May studying these guys in Costa Rica:
My work was entirely at La Selva Biological Station, and I accrued a nice little collection of sightings despite very little time devoted solely to herping. Since these were mostly isolated unconnected sightings over two month’s time I’m going to go narrative-light here and just lay on the pictures. Those are what everyone loves anyways.
Frogs
Oophaga pumilio – dirt common, I hardly ever even took their pictures
Saw most of these at Cantarana swamp one night, I’ve forgotten some of the IDs (and my books are in another state right now):
Agalychnis saltator
Rana vaillanti
Cruziohyla calcarifer – someone brought this in to the office from the suspension bridge one night. I was thoroughly enthused:
young Rana warszewitschii, my vote for the worst species name ever
Turtles
Rhinoclemmys funerea – common in or near the streams
Rhinoclemmys annulata – less common, found farther from water
Kinosternon leucostomum
I also saw but did not get to photo Chelydra serpentina
Lizards
Anolis capito – probably my favorite Anolis
Anolis limifrons
Anolis oxylophus
Basiliscus plumifrons
Corytophanes cristatus – I love these things. They get a lot of abuse because their defensive behavior seems to be to act like a leaf. This one got punted because it sat on a trail like a dead leaf. Luckily it was a glancing blow and not a full step. I found another while tromping through some undergrowth using a stick to push branches out of the way, and I accidently batted it 2 meters away.
Ameiva
Lepidophyma flavimaculatum – lived under our office step, but rarely came all the way out
Gonatodes albogularis
Thecadactylus rapicauda – I’m a big gecko fan, so when I finally caught this I was bouncing off the walls
Snakes
Ninia sebae
Dendrophidion percarinatum
Pseustes poecilonotus, destroyer of birds. We filmed these depredating nests of our study species
Lampropeltis triangulum, the biggest meanest one I’ve ever seen
Sibon nebulatus
Sibon longifrenis
Coniophanes fissidens
Chironius grandisquamis
Scaphiodontophus annulatus
Venomous snakes are so common at La Selva it made nest-searching downright gnarly. I can’t tell you how many of these I found by almost stepping on them:
Porthidium nasutum
Bothrops asper
Right on the trail:
Bothriechis schlegelii – not only do I have to worry about what I step on, I have to watch where I’m going for stuff like this at head hight
This individual sat on the same perch for three weeks.

Re: 2 Months at La Selva, Costa Rica
Cool!
When I was at La Selva years ago the only snake we saw was a Scaphiodonthophis. Cool to see one posted from the same area! First time I ever see that posted.

Re: 2 Months at La Selva, Costa Rica
WOW, that is a mind-blower, certainly among the very most thrilling neo-tropical posts. Lots of creative images. BUT, what kind of bird? Some kiond of Ant-shrike or some such thing?
Re: 2 Months at La Selva, Costa Rica
The Lampropeltis triangulum is amazing! hounderensis or some other obscure central/south milk?

Re: 2 Months at La Selva, Costa Rica
Very cool post, I loved the diversity. But herping in the tropics with that head of hair must have been brutal, I would have shaved it off! Any stories of weird creatures living in your hair or it getting in your way?

Re: 2 Months at La Selva, Costa Rica
About two months after my work in CR ended, after doing a month's work in Venezuela and returning home long enough to decide to cut my hair, I decided it was time to rip this little annoyance out of my head. He had been there since the last week in CR.Viridovipera wrote:Very cool post, I loved the diversity.

It now lives in a specimen jar at home.

Re: 2 Months at La Selva, Costa Rica
So nice. We thought we were special with our Cruziohyla this summer. People were saying none had been turned up, and on the bridge at that. We spent almost 4 straight nights hiking specific trails for eyelashes without luck. Super jealous of that one.

Re: 2 Months at La Selva, Costa Rica
Great pics. I was lucky enough to spend 3 days there a few years back. Didn't see nearly all what you saw, but it was great. Did see some Aracari's raiding a cavity nest and loads of small herps, but no snakes. I do recall a yellow headed gecko as well and many great orchids. Makes me want to dig out my slides!

Re: 2 Months at La Selva, Costa Rica
A Costa Rica post with turtles included is always a win.
The milk is probably L.t. micropholis.

I believe the CR triangulum are nelsoni for what thats worth.
Cool herps, any more shots of antbirds?

I suppose I can upload my bird photos and make a bird post sometime soon. I dont have many shots of the antbirds out of the hand because they are so skulky. I did get this video though:thibbitts wrote:Cool herps, any more shots of antbirds?

Re: 2 Months at La Selva, Costa Rica
Righteous post! I second the botfly shudder... How painful was its removal? Any infection?
The Milksnake is L. t. stuarti , if one accepts Williams' "25 subspecies" taxonomic proposal - micropholis is much further south, near the Colombian side of Panama and south; nelsoni is found along Mexico's central pacific coast; hondurensis is in Caribbean Honduras and Nicaragua; gaigeae is found in the Central Highlands and Caribbean slopes of CR, and is solid black as an adult. Very cool, regardless.

Re: 2 Months at La Selva, Costa Rica
Nice pictures !!
Im actually keeping a L.triangulum hondurensis and since I love naturalistic terrariums Im searchin a pictures of the habitat of that snake to print and put on the back of my cage. Do you have some I can use? Better if take on the level of the ground.....
thanks you !
