We were staying at the recently renovated Costa Rica Bird Observatory house at Madre Selva in the Talamanca range, an area of high biodiversity richness and home to many endemic birds.
Three different ringing sites are operated from the base each with slightly different species being caught. This is the ringing table at CRBO ready for action.
Some birds we caught there included several Yellow-thighed Finches
Nice legs!
a Black-faced Solitaire which has a wonderful flutey song which unfortunately makes them targets for capture for the caged bird trade.
These were nice to age, hatch year birds having clear contrast in the Greater Coverts
Black-cheeked warblers
Ruddy Treerunner
Sooty -capped Bush Tanager
and a rather smart Collared Trogon
As well as residents we were catching some migrants too like this Black and White warbler
and a Louisiana Waterthrush
Residents and Migrants have different record sheets and rings which kept us on our toesAt the "Lake" site the nets are in forest around a lake with a sheltered ringing base in a summer house
We cleared some old net lanes with a machete to increase the number of nets.
Our star birds here were a Common Paroque which we had seen displaying around the lake at dawn on previous days
this Flame-throated Warbler
a Streak-breasted Treehunter which lives in a 2 foot burrow!
Black and Yellow Silky-Flycatcher, a highland endemic
and a Brown-capped Vireo.
Collared Redstarts were fairly common
but nice to catch a Slate-throated Redstart too
Of the migrants caught, Wilson's Warblers were the commonest
with a few Black-throated Green Warblers
and quite unusual, a juvenile Ovenbird
and a Summer Tanager
The third site is more open woodland and farmland
but sometimes the cows took rather too much interest in the nets!
and several Grey-breasted Wood-Wrens too
Two beautiful Resplendent Quetzels sat in a tree above but not in a net one day. Hummingbirds were frequent captures at Madre Selva - more about those in the next blog.....
