BIRD CHECKLIST (Nomenclature follows the 2012 AOU checklist of North American Birds)
Callyn D. Yorke, Ph.D.
The area covered by this checklist includes the road from Pital to the Lodge, surrounding roads to neighboring farms; the Rio San Carlos near the lodge to the Rio San Juan; a small portion of the Rio San Juan near Boca San Carlos. Habitats included are primary and secondary rainforest, rivers and streams, riverine forest, sandbars and mudflats, pastureland, plantations, gardens, weedy roadsides and fields. This list shows the many bird species you may encounter on a 3-5 day visit as you explore the excellent birding spots at and nearby the lodge. The codes reflect the chances an average birder will have at observing or hearing a particular species. Keep in mind that some resident breeding birds (e.g. Great Green Macaw) become relatively scarce or entirely absent seasonally.
It should also be noted that this part of northern Costa Rica contains a wide variety of birds (390 species on this list) owing to many microhabitats within the general habitats listed above. For example, some species (e.g. Agami Heron) are found only in the quiet backwaters of rainforest lagoons. Many other bird species of the rainforest have a unique and often limited set of ecological requirements. Thus, by visiting a variety of habitats and paying attention to subtle changes within a particular habitat, the careful observer may be rewarded with sightings of some rare and beautiful species.
1: Permanent resident. 2: Wintering species (Sept.-April). 3: Passage migrant only – usually spring & fall . 4: Sporadic visitor from upslope or elsewhere. 5: Out of expected range, accidental. ?: Status unclear; more data needed.
SIGHTING FREQUENCY CODES
C: common, seen or heard daily. FC: fairly common. usuallyseen or heard daily. U: uncommon. May be seen weekly but could be missed. R: rare. Seen or heard monthly; local and/or secretive habits. VR: very rare. Low population numbers; difficult to find, even in the right habitat. X: Occasional: Unexpected; fewer than 5 documented occurrences.
This bird list represents the latest revision (2012) following the previous editions of 1998, 2000, 2001 and 2002. In addition to my field studies in the region (1997-2012), the LDL bird list is the result of many hours of field observations by several experienced ornithologists and other biologists working in the area during the past twenty years. Indeed, the LDL bird list continues to be a collaborative effort and is a significant contribution to ornithology in northern Costa Rica. I am indebted to the following individuals for their excellent work (in alphabetical order): Oscar Artavia, Didier Castro, Mark Digirolamo, Adolfo Gonzalez, Tyler Hicks, Dan Keller, Gerard Phillips, and Nicholas Wilkinson.
