Legal Harvest of Shorebirds and Resident Game Birds on a Caribbean island: A Martinique Case Study

Legal hunting practiced under regulatory frameworks is not always assessed for its sustainability. The lack of harvest data is of particular concern in the case of birds occurring on islands. Resident species on islands often exhibit limited geographic ranges and inherently small population sizes, rendering them particularly susceptible to environmental and anthropogenic threats. Islands also support seasonally fluctuating populations of migratory species, providing essential habitats for stopovers and non-breeding periods. Within this context, the sustainability of gamebird harvest practiced on islands within a regulatory framework needs to be evaluated to inform management and prevent negative impacts on populations. Here, we present a case study of an island-wide assessment of bird hunting estimates, based on data available from a legal hunting program, in Martinique, a tropical oceanic island part of the Caribbean biodiversity hotspot. Our objectives were to determine the magnitude of gamebird harvest, track changes in harvest levels over time, and assess harvest sustainability. Our assessment, which is based on hunting logbooks and hunter surveys between the 2012-2013 and 2021-2022 hunting seasons, provides harvest estimates for two groups of migratory species, shorebirds (Charadriidae, Scolopacidae) and teals (Anatidae), and two groups of resident species (Columbidae and Mimidae). In Martinique, harvest management measures, combined with increased hunters engagement and enforcement of regulations, has led more stringent harvest regulations, improved compliance from hunters, and a reduction of Martiniques national shorebird harvest. However, considering continued and rapid shorebirds population declines across the Western Atlantic flyway, shorebird harvest assessment at the flyway level remains a priority.

A national assessment of waterbird hunting in coastal wetlands of Suriname, south America

The central northern coast of South America has extensive wetlands critical for waterbird conservation. While waterbird harvest occurs in the region, the impact on species population dynamics remains unclear. This study assesses waterbird hunting in the coastal wetlands of Suriname, addressing: (i) the extent of waterbird harvest, (ii) changes in harvest magnitude over time, and (iii) the motivations and methods used by hunters. We collected data via a national survey of licensed hunters in 2006 and 2016 using structured interviews. A Bayesian hierarchical model was used to analyze the data. We estimated harvest levels for 11 species and three groups (small herons, small shorebirds, large shorebirds). For most species, mean harvest per hunter significantly decreased from 2006 to 2016, except for blue-winged teal and migratory shorebirds. Most hunting was for non-commercial purposes (personal consumption and recreational). This is the first national assessment of waterbird hunting in Suriname. Harvest levels vary by species, and the sustainability of these levels remains uncertain. Managing hunting in Suriname requires addressing both legal and illegal hunting. Given Surinames importance for waterbirds, particularly species like the scarlet ibis and migratory shorebirds, it should be a priority for conservation efforts.
