Bahamas (Oliver 1948). This species occurs primarily on
twigs and small branches of the canopy, and is assigned to the
“twig” ecomorph (Beuttell and Losos 1999). Novo Rodríguez
(1985) first reported communal nesting in A. a. angusticeps
on Cayo Francés, Cuba. He described a female attempting
to enter a hole in the trunk of a palmetto tree. Upon examining the hole, the opening of which was 1.6 x 1.0 cm and
1.6 m above the ground, he found 65 developing eggs and
1,625 eggshells. On Cayo Coco, Cuba, Estrada (1993) also

and elsewhere in a rocky fissure he found four intact eggs and
about 80 shells/m2 in an area of about 2.5 m2.
On 28 July 2013, while walking the “Beach Trail” of
South Bimini (25.7022˚N, -79.3019˚W), we observed an
instance of communal nesting in A. a. chickcharneyi. We captured an adult female on the trunk of a Ficus sp. tree and realized that she had been covering a hole in the tree, her body
position suggesting that she was exiting the hole. Two days
prior, we had captured another female in the same location
on this tree. The hole was 1.12 m above the ground, and the
opening was 3.5 x 1.5 cm. Inside the hole, we could see at least
seven eggs, packed together and touching one another (Fig. 2).
Because we did not wish to disturb the eggs, we were unable to
determine whether additional eggs were packed into the hole
or to count any eggshells that might have been inside.
Communal nesting in lizards may occur when suitable nesting sites are rare or if adaptive benefits accrue from aggregation
of eggs (Radder and Shine 2007). Communal nests, although
infrequently described for West Indian Anolis lizards, may be
more common than the number of reports would suggest.
