If you hear this sound while catching crabs in a wetland in Jamaica, don’t be startled. It’s not a duppy – it might be two Jamaican crocodiles doing their thing.
It’s mating season for our native American crocodile (Crocodylus acutus), where big males bellow and splash to impress females.

Rooster how was your day?
It was very interesting as you can see the wildlife professionals were here in the crocodiles business. For all my years working with crocodiles I have never seen them getting it on until today.
Wow, What a day?

Say hello to pirate the happy crocodile at the Holland Bay Crocodile Sanctuary. The sanctuary is home to several of our Jamaican crocodiles. The sanctuary is doing well after the hurricane Melissa . However we have to do what we can do to help crocodile conservation.

A fungus from the Blue Mountains Jamaica.
Did you know Jamaica has its own endemic bamboo species? 🌿
It’s called Chusquea abietifolia, found mainly in the high-elevation forests of the Blue and John Crow Mountains. It forms dense thickets, supports wildlife, and only flowers every few decades before dying back, a classic bamboo behaviour.

While carrying out assessments after Hurricane Melissa in the cloud forest of the Blue Mountains, we came across a huge Eucalyptus tree blocking the path. Residents said a lightning strike hit the tree. Even without electricity in the homes, they still saw sparks coming from a conduit.

I just read a paper reporting that the invasive mosquito Aedes vittatus has been confirmed in Jamaica for the first time.

A special big up to a member of the social media family who found this snake in southern Manchester.
It is likely Tropidophis jamaicensis – the Jamaica dwarf boa – endemic to Jamaica and listed as endangered. This small, non-venomous snake spends most of its time hidden in leaf litter and rocks

Look at what I found during my assessment of the Blue Mountains after Hurricane Melissa. It is our endemic and endangered Red-eyed Frog (Eleutherodactylus nubicola). This species is found nowhere else on Earth and depends on the cool, wet cloud forest of the upper mountains.

An AudioMoth and a Titley Chorus acoustic recorder were deployed before Hurricane Melissa.
I’ll be taking them down soon to review the recordings and see which birds and bats passed through the area during and after the storm.

Did you know that hurricanes affect each mangrove species differently in Jamaica?
🌿 Red Mangrove (Rhizophora mangle)
If a red mangrove is knocked down, it usually dies because its prop roots are easily damaged.
🌿 Black Mangrove (Avicennia germinans)

The post-hurricane wildlife monitoring has begun.
Here I am deploying an @AudioMoth in the forests of the John Crow Mountains, one of the areas impacted by Hurricane Melissa.
This device records sounds from wildlife throughout the day — capturing 1 minute of audio, then sleeping for 10 minutes,

A lovely flower I spotted on the ReggaeHikers trail today the Spurred Butterfly Pea (Centrosema sp.).
These vines help enrich the soil and attract bees + butterflies.
What does it remind you of?

The mongoose was introduced to Jamaica in 1872 to control rats in sugar cane fields but it quickly became one of the worst invasive species on the island. It preys on our native lizards, snakes, frogs, birds, and their eggs, pushing some species to extinction and others to the brink.

A special big up to Christian for sharing a video of our Jamaican Fruit Bat enjoying a fruit snack! 🦇🍉
Did you know these bats play an important role in seed dispersal across Jamaica? They help our forests recover—especially after storms like Hurricane Melissa.
