Isla San Jose
Isla Boca Brava, Chiriqui Prov., Panama
7 May, cont.
removed alphas had been released. Julie and
I hiked up from the southern Sandy beach
till we heard Lance-Tailed Manakin vocalizations
to the West. We followed them and found
two unbanded definitive-plumage males who
responded readily to my mimicked down-
whistle and who came quite close. The
habitat on San Jose is at a much more
developed successional stage than that on Boca Brava.
The canopy is high and dense - it's +/- 15m
in most areas of Boca Brava, but was more like
20-25m on San Jose. The understory was
very open and easy to walk through with no
gresses and few if any shrubs. Small trees
of about 3m in height were abundant and
there were plenty of potential nest sites, though
these small trees were generally 'cleaner'
and straighter than Boca Brava saplings.
I saw no Euphorbiaceae sp. saplings or trees,
but I didn't look too hard. We returned
along the coast and noted the volcanic
appearance of the rocks - they are very
fluid in morphology, and streaked with veins
of a bright green stone that is something
like serpentinum or jade. See following page
for a map of San Jose.
