However, there is little consensus regarding the impact of landscape changes on the likelihood of species extinctions. We conducted a literature search using Scopus and ISI Web of Knowledge databases to identify studies where bird species were used to estimate threshold responses to landscape changes. We obtained a list of 31 papers published from 1994 to 2018, with 24 studies conducted at temperate latitudes and seven in tropical regions. Nineteen studies were based on species-level assessments, and investigators used a variety of response variables such as probability of detection and occurrence to detect threshold responses. Eight studies were based on communities, and species richness and abundance were primarily used to detect threshold responses. Four studies included both communities and species-level assessments. Methods used to identify threshold responses varied among studies, but most relied on either regression models to visually identify values from graphs or piecewise regression to estimate a specific threshold value. Although the limited number of studies and their variety of approaches and methods prevented a formal meta-analysis, we found that mean threshold responses in studies that reported either a range or a single threshold value were 27.9% at temperate latitudes (range = 1.3–90%; N = 11) and 33.6% at tropical latitudes (range = 20–50%; N = 7). Considering only studies where single threshold values were reported, the mean habitat cover threshold was 11% for studies conducted at temperate latitudes (N = 3) and 29.5% for studies in the tropics (N = 4). These crude estimates suggest that tropical species might be more susceptible to habitat loss than temperate species. Although application of the threshold concept is still controversial, the number of studies using this approach is increasing because the results of such studies may have direct application to conservation strategies and restoration of landscapes for bird conservation. Resumenes Una revisión de las respuestas de umbral de las aves a los cambios de paisaje en todo el mundo Identificar el umbral de la cobertura del hábitat más allá de la cual especies de aves se pierden localmente, es útil para comprender las consecuencias biológicas de los cambios en el paisaje. Sin embargo, existe poco consenso respecto al impacto de los cambios en el paisaje sobre la probabilidad de extinción de las especies. Llevamos a cabo una búsqueda bibliográfica utilizando las bases de datos Scopus e ISI Web of Knowledge para identificar estudios en los que se utilizaron especies de aves para estimar las respuestas de umbral a los cambios en el paisaje. Obtuvimos una lista de 31 artículos publicados de 1994 a 2018, con 24 estudios realizados en latitudes templadas y siete en regiones tropicales. Diecinueve estudios se basaron en evaluaciones a nivel de especie, y los investigadores utilizaron una variedad de variables respuesta, como la probabilidad de detección y ocurrencia para detectar respuestas de umbral. Ocho estudios se basaron en comunidades, y la riqueza y la abundancia de especies se utilizaron principalmente para detectar respuestas de umbral. Cuatro estudios incluyeron tanto comunidades como evaluaciones a nivel de especie. Los métodos utilizados para identificar las respuestas de umbral variaron entre los estudios, pero la mayoría se basó en modelos de regresión para identificar visualmente los valores de los gráficos o la regresión por partes para estimar un valor de umbral específico. Aunque el número de estudios es limitado y su variedad de enfoques y métodos impidieron un metanálisis formal, encontramos que las respuestas de umbral promedio en los estudios que informaron un rango o un solo valor de umbral fueron 27.9% en latitudes templadas (rango = 1.3–90%; N = 11) y 33.6% en latitudes tropicales (rango = 20–50%; N = 7). Teniendo en cuenta solo los estudios en los que se informaron valores únicos de umbral, el umbral medio de cobertura del hábitat fue del 11% para los estudios realizados en latitudes templadas (N = 3) y del 29,5% para los estudios en los trópicos (N = 4). Estas estimaciones crudas sugieren que las especies tropicales podrían ser más susceptibles a la pérdida de hábitat que las especies templadas. Si bien la aplicación del concepto de umbral todavía es controversial, el número de estudios que utilizan este enfoque va en aumento, debido a que los resultados de dichos estudios pueden tener una aplicación directa a las estrategias de conservación y restauración de paisajes para la conservación de aves.
