“…Furthermore, our results also agree with the fact that wetland development and establishment of recent plant genera used by reed buntings (e.g. Phragmites , Cladium , Typha ) (Worobiec and Worobiec 2019, Alambiaga et al 2021) should pre‐date their expansion.…”

The reed bunting, Emberiza schoeniclus (Linnaeus 1758), is the only member of the genus adapted to Mediterranean wetlands, where some subspecies are critically endangered. The first complete mitogenome of the eastern Iberian reed bunting (E. s. witherbyi) is presented here and compared with an unpublished mitogenome obtained in northeast Asia (most likely E. s. pyrrhulina). Genetic distance analyses are consistent with the new reed bunting data corresponding to two distinct lineages of E. schoeniclus. A new fossil-calibrated phylogeny suggests that open forest buntings have suffered two rapid speciation events from Late Miocene to Pleistocene, that seem to be correlated with major climatic changes and habitat shifts. Adaptation to a new ecological niche (i.e. wetlands) could have favoured the reed bunting expansion across the Palearctic. The high intraspecific variation observed today could result from the establishment of resident populations within small areas, potentially acting as a climatic refuge.

“…This may be compromised by recurrent cold or rising water levels. In a study in southern Spain, an increase in water level during the breeding period negatively affected the population of the species, as higher water levels destroyed nests (Alambiaga et al 2021). For our own data, a significant positive correlation between water level and juvenile/adult ratio was found when the water level of the whole breeding season and the average annual water level was considered.…”

In recent years, the breeding populations of many migratory songbird species have declined in the Carpathian Basin. However, there may be significant differences between different geographical regions, as most species have a much higher chance of successful breeding in protected areas. This is also the case for the Moustached Warbler, one of the most habitat-specialist passerine. It colonises only perennial, unharvested reedbeds, therefore its conservation management is essential. We studied the population changes of this species between 2001 and 2022 at Lake Kolon in Izsák, based on bird ringing data from 10–24 July. Data of 12,817 ringed and 5,075 recaptured birds were used in the analyses. The annual capture rate decreased significantly during the study period. The proportion of juveniles was higher at higher water levels during the whole breeding season. In contrast, when looking at winter and first and second broods separately, water level had no effect on the juvenile/adult ratio. This is because the birds compensate for unsuccessful first broods by increasing the proportion of second and replacement broods. If the first broods are successful, the ratio of second and replacement broods will be lower. As reed management is practically non-existent in this area, the perennial reedbeds provide suitable nesting conditions for the species. Changes in the wintering sites may be responsible for the declining trend. Protection of the area is of particular importance for the conservation of the species.

“…Si bien, en esta ocasión, los puntos de escucha de cinco minutos se repartieron cada 300 metros del recorrido, en lugar de 200 metros, en sólo dos días consecutivos, para evitar duplicidades por posibles movimientos de ejemplares dentro del humedal. Al formar parte de un estudio más amplio de paseriformes palustres con una red de rutas que se repite cada año (Alambiaga, et al, 2021), el número de puntos de escucha se adaptó a la accesibilidad y a las condiciones del humedal presentes en la primavera de 2021, con el objetivo de cubrir la máxima superficie y la más amplia representación de hábitats posible.…”

“…El humedal que registra mayor población sigue siendo Las Tablas de Daimiel, que con 46-48 parejas reproductoras ha visto recuperada su población, triplicándose con respecto a la de 2015 (Monrós et al, 2017), y cuadriplicándose a medio plazo (2012( -2019( , Alambiaga et al, 2021. Las Tablas de Daimiel se mantiene como el segundo humedal más importante para la especie en España (véase tabla 8), aunque muy lejos aún de las 90-120 parejas estimadas en 2005 (Atienza, 2006).…”
