~Welcome to the city where the heat is on….
This past weekend, I was very fortunate to have a chance to spend time looking for herps in Miami (Florida, USA) with my colleagues Josh, Tim, and Renata. Our main objective was to collect some brown anoles (A. sagrei) for Josh’s egg incubation thermal spike experiment, and to survey possible location to set up another experiment I will conduct this summer on maternal nest-site behavior of Puerto Rican crested anoles (A. cristatellus).

Nonetheless, we had some time to survey for herpetofauna at multiple spots including Pinecrest, Matheson Hammock, Coral Gables and Key Biscayne.

Pinecrest – along Red Road and Snapper Creek Canal
We spent almost four hours here and found:
Brown anole, Crested anole, bark anole, Green anole, brown basilisk, Knight anole, African rock agama, and a Green iguana (respectively: Anolis sagrei, Anolis cristatellus, Anolis distichus, Anolis carolinensis, Basillicus vittatus, Anolis equestris, Agama agama, and Iguna iguana).

A. cristatellus and a lot of Agama agama living in the rock wall in the parking lot.

Key Biscayne – Crandon Park and downtown
A. cristatellus, A. distichus, A. carolinensis and Ctenosaura similis (black spiny tail iguana). It was very windy by the beach!

Coral Gables – Peacock Park
A. sagrei, A. cristatellus, and Leiocephalus carinatus (Northern curly-tail lizard). This park was quite busy with people.

Overall, we saw 13 species of herpetofauna (a snake and turtle not listed) despite the windy condition and overcast sky. It was a very fun and productive weekend, and I look forward to spending more time down in Miami over the summer!

If you would like detailed field notes, please feel free to contact me!

Old dancing feet…the case of old male blue-footed boobies

Dance is like wine; it matures with every performance.
– Alarmel Valli (classical Indian dancer)

Unfortunately, this is not the case for male blue-footed boobies (Sula nebouxii). In their world, males show off their extravagant blue feet and “dance” to attract females. The more brighter the blue on your foot, the more attractive you are because this shows that you know how to take care of yourself.
A study by Torres and Velando (2007) showed that older males, while more experienced, are not as attractive because they cannot keep their bright coloured blue foot. Unfortunately, as the birds age, their immune system gets weaker and their body can not dedicate so much energy into making their feet look nice as much as they want to.

Here’s a great video of what the dance looks like!

Fun fact: The name “booby” comes from the Spanish word “bobo” which means clown!
