Introduction
Conservationists have an urgent need to use science as a tool to effectively manage biodiversity problems. While my career is mainly focused on technical assistance—covering a wide variety of projects in ecology, bird migration and conservation biology—my own research includes several small projects. I am interested in computational analysis of large datasets at the population level, to point out situations that can be addressed more specifically following a field ecology perspective. Some topics I focus on are mediterranean habitat management; ecology of poorly-known species (Cecropis daurica, Lanius species); food resource use during bird migration; and how agriculture, hunting, climate change, citizen science and local engagement can interact in information-conservation-ecology dynamics

Conclusiones:
1. La ganga ortega ha sufrido un declive generalizado de sus efectivos del 43% en España peninsular.
2. Este declive ha llevado a la reciente catalogación de su población peninsular como "En Peligro" en el Libro Rojo de las Aves de España 2021 (3).
3. Los mayores declives se han dado en los núcleos poblacionales al norte de la pení...
La ganga ortega (Pterocles orientalis) es una especie amenazada de las estepas ibéricas, donde ha registrado un descenso significativo en los últimos 15 años. La especie está amenazada por la pérdida o degradación de su hábitat (intensificación agrícola). A efectos de gestión es fundamental conocer en detalle las zonas de mayor probabilidad de ocur...
Using EURING data and geolocation, we describe migration routes and the nonbreeding range of Red-rumped Swallows breeding in the Western Palearctic. One bird ringed in southern Spain and recovered in southern Morocco indicates southwestern migration; geolocator data from five birds from central and eastern Iberian Peninsula confirm migration to var...
Sown seeds are a key component of many farmland birds’ diets due to natural food shortages in autumn and winter. Because these seeds are often treated with pesticides, their ingestion by birds can result in toxic effects. For risk assessment, data on treated seed toxicity should be combined with information about exposure risk for wild birds and th...
Se presentan los principales valores ambientales que definen la geografía de la provincia de Toledo: altitud sobre el nivel mar; distribución geográfica de los principales cauces hidrológicos; usos generales de suelo; comarcas; y población de los diferentes municipios. A partir de estos mapas, y siguiendo los límites comarcales, se propone la divis...
El presente volumen del Anuario Ornitológico de Toledo 2014-2018 contiene
siete artículos y dos notas breves: se repasan las poblaciones de carricerín cejudo, cormorán grande, morito y las aves acuáticas; se estudia la dispersión en la provincia del águila de Bonelli y sus amenazas; se describen variables ambientales de interés para las aves en la...
Results of the 2019 national census of Pin-tailed Sandgrouse (Pterocles achata) and Black-bellied Sandgrouse (Pterocles orientalis) in Spain
Transcurridos 14 años del primer censo nacional sobre la especie, en 2019, con la inestimable colaboración de las comunidades autónomas y miles de voluntarios, se ha vuelto a repetir el trabajo que actualiza la situación poblacional de la especie.

Moult is a vital and endogenously controlled process in the avian life. However, birds may modulate their feather renovation
properties, such as the extent of moult, based on exogenous factors. Despite the large body of knowledge about moult
patterns, numerous questions remain unclear. In this study, we aimed to improve our knowledge about the fact...
Data from remote sensing are often used as proxies to quantify biological processes, especially at large geographical scales. The normalized difference vegetation index (NDVI) is the most frequently used proxy for primary productivity. Assuming a direct, positive interrelation between primary and secondary production in terrestrial habitats, NDVI i...
Asynchrony in cereal crop sowing within partridge home ranges makes pesticide‐treated seeds a potential food resource during at least three months per year.
Current practice of basing pesticide risk assessment on single‐field scenarios is therefore unrealistic and can lead to underestimation of risks to birds.
The selection of sown fields during...
La golondrina dáurica, Cecropis daurica, es una especie que durante las últimas décadas se ha expandido a nuevas áreas y su población se ha mantenido estable o incrementado. Construye sus nidos bajo construcciones edificaciones humanas, con especial atracción hacia puentes y pasos de carreteras. Utilizando sistemas de información geográfica (SIG),...
Shrikes species (Lanius sp.) share common ecological traits, but certain variability has been observed. Although there is some consensus on their global conservation problems, research so far don´t describe them specificly or these problems don't affect all the shrikes species. Experts consider that Woodchat shrike (Lanius senator) is threatened by...
The Iberian Peninsula is a wintering area for an estimated 300 million birds. Most insectivorous birds winter in the southern half of the Peninsula, where mild mid-winter temperatures ensure the availability of insects. However, case studies of habitat use by specific species during winter are still rare. A species of particular interest is the Eur...
