Black-collared Hawk at San Miguelito Wetlands


On March 8, 2014, Georges Duriaux, Liliana Chavarría and Manfred Bienert visted the San Miguelito wetlands (Humedales de San Miguelito) RAMSAR site in Rio San Juan department.  After traveling 4½ km by boat up the SE shoreline of Lake Nicaragua, the birders entered the Piedras and Camastro rivers which together form the marshy wetlands.  During the course of the morning, they observed a total of 84 bird species, including five species of kingfisher and a similar number of duck species.  Noteworthy were two large groups of Muscovy Duck (Cairina moschata), each comprising 30-35 individuals (in Nicaragua this species is generally found in much smaller groups).  The birders also found 10 different species of herons.  A group of 15 Yellow-crowned Night-Herons (Nyctanassa violacea) appeared to be a migratory flock since this species generally is not otherwise found in groups and typically prefers salt or brackish water habitats.

Other migrants included two large kettles--of around 500 birds each--of Turkey Vultures (Cathartes aura) making their way slowly northward.  Among them were a dozen Swainson's Hawks (Buteo swainsoni) and six Broad-winged Hawks (Buteo platypterus).  In addition to these, the birders observed eight other raptor species including Lesser Yellow-headed Vulture (Cathartes burrovianius) and nearly 25 Ospreys (Pandion haliaetus).  But the day's real highlight were six Black-collared Hawks (Busarellus nigricollis), a noteworthy concentration of individuals given that this species is considered rare in Nicaragua.

Throughout the wetlands, abandoned woodpecker holes were being used by Mangrove Swallow (Tachycineta albilinea) and Gray-breasted Martin (Progne chalybea).  Other species of interest included Southern Lapwing (Vanellus chilensis), Franklin´s Gull (Leucophaeus pipixcan), Mangrove Cuckoo (Coccyzus minor), Prothonotary Warbler (Protonotaria citrea) and Nicaraguan Seedfinch (Oryzoborus nuttingi).

2nd Annual Great Green Macaw Photo Contest

 
Fundación del Río, a Nicaraguan NGO that has devoted itself for more than two decades to sustainable development and environmental conservation in the Río San Juan region, announces its second annual Great Green Macaw photography contest from April 30-May 3, 2014.

For several years, Fundación del Río has undertaken a cross-border (with Costa Rica) conservation program to save the Great Green Macaw (Ara ambiguus). Birders and photographers of all skills levels are invited to join in this year's event to search for and photograph this rare and emblematic bird. Registration is USD 100, and a prize of USD 700 will be awarded for the best photo of a Great Green Macaw, with a second place prize of USD 300.

During last year's inaugural expedition, in addition to the "target" species, participants also saw Scarlet Macaw (Ara macao), Red-throated Caracara (Ibycter americanus), Chestnut-colored Woodpecker (Celeus castaneus), Green Ibis (Mesembrinibis cayennensis), Common Potoo (Nyctibius griseus), White-fronted Nunbird (Monasa morphoeus), White-ringed Flycatcher (Conopias albovittatus), Giant Cowbird (Molothrus oryzivorus), Shining Honeycreeper (Cyanerpes lucidus) and much more.
