Nesting success and productivity of a declining European turtle dove (Streptopelia turtur) population in western France

“…This rate was similar to values previously reported in Britain (Browne & Aebischer 2004: 34.4%, Browne et al . 2005: 41.3%), but lower than reports from elsewhere in France (Lormée 2020: 37–66%, estimated over the 2000–19 period), Spain (Rocha Camarero & Hidalgo de Trucios 2002: 36–58%) or Portugal (Dias 2016: 56–75%). Our nest monitoring totalled 1210 exposure days, leading to a DSR of 0.959 ± 0.006 (model S(.…”

“…Except for the high value of 2.71 young reported in Portugal in 1994 by Fontoura and Dias (1996), our results yielded a higher mean productivity than other studies. Values from Portugal reported by Dias (2016) ranged from 1.68 to 2.14, and in Britain, Browne and Aebischer (2004) reported 1.3 young per pair in 1998–2000, and Murton (1968) reported 2.1 in the 1960s (1960–62, 1966). In their recent review, Carboneras et al .…”

“…2020), yet little is known about breeding productivity in this species. In addition, most studies were carried out several decades ago and on a restricted array of habitats, such as UK farmlands (Murton 1968, Browne & Aebischer 2004) or southern European forests (Fontoura & Dias 1996, Dias 2016). It is therefore unclear whether productivity is low in other parts of the species' breeding range and whether it remains a plausible hypothesis to explain recent population declines.…”
