“…1). This species are socially monogamous; both mates contribute to nest building, incubation and the feeding of nestlings (Moreno et al, 2005; Espíndola-Hernández et al, 2017). Furthermore, this species has shown latitudinal differences in anti-predatory behavior (Ippi et al, 2011, Ippi et al, 2013), clutch size (Quirici et al, 2014), nest architecture (Botero-Delgadillo et al, 2017a), corticosterone levels (Quirici et al, 2014), telomere length (Quirici et al, 2016), and high levels of gene flow (Gonzalez and Wink, 2010) with exception of the northernmost isolate population (Yáñez et al, 2015; Botero-Delgadillo et al, 2017b).…”

Latitudinal gradients are well-suited systems that may be helpful explaining distribution of haemosporidian parasites and host susceptibility. We studied the prevalence, diversity and drivers of haemosporidian parasites (Leucocytozoon, Plasmodium and Haemoproteus) along a latitudinal gradient (30°–56° S), that encompass the total distribution (~3,000 km) of the Thorn-tailed Rayadito (Aphrastura spinicauda) in the South American temperate forests from Chile. We analyzed 516 individuals from 18 localities between 2010 and 2017 and observed an overall prevalence of 28.3% for haemosporidian parasites. Leucocytozoon was the most prevalent parasite (25.8%). We recorded 19 distinct lineages (13 for Leucocytozoon, five for Plasmodium, and one for Haemoproteus). Differences in haemosporidian prevalence and diversity by genus and type of habitat were observed in the latitudinal gradient. Further, we support the existence of a latitudinal associate distribution of Leucocytozoids in South America, where prevalence and diversity increase toward higher latitudes. Distribution of Leucocytozoon was associated with sub-antarctic habitat (higher latitude) and explained by cold temperature and high precipitation. On the other hand, we lacked to find a latitudinal associate pattern for Plasmodium and Haemoproteus, however low prevalence and high diversity were recorded in areas considered as a hotspot of biodiversity in Central Chile. Our findings confirmed the importance of habitat and climatic variables explaining prevalence, diversity and distribution of haemosporidian parasites in a huge latitudinal gradient, belonging the distribution of the Thorn-tailed Rayadito in the world's southernmost forests ecosystems.

“…So many arguments in favor of a bias of investment of the mothers toward males to increase their fitness. This question cannot be solved through this study, but our study show clearly that a female can favor one of both sexes as it is the case in many other species (Espindola‐Hernandez, Castaño‐Villa, Vásquez, & Quirici, ; Pluhacek et al, ). Mechanisms that elicit this favor in mothers remain to determine: that could be the size of the chicks or only their sex as demonstrated in some altricial species (Espindola‐Hernandez et al, ; Mainwaring, Lucy, & Hartley, ; Stěhulová et al, ).…”

Sex is a trait which leads mothers to invest asymmetrically in their young, especially in species with a strong dimorphism. Authors usually consider that members of the largest sex require the most investment by mothers. In other cases, mothers care preferentially for members of the sex that increase their fitness, e.g. males, in numerous species. In quail, a precocial bird, mother seems to take more care of their males which are more sensitive to their separation. This study investigates the influence of chicks’ sex and brood's sexual composition on the maternal behavior of quail. We evaluated three batches of mothers, composed of (a) unisex broods of males (MM), (b) unisex broods of females (FF), and (c) mixed sex broods (Mx). We recorded mother‐chick interactions during 11 days of mothering. We found that MM mothers spent more time warming their chicks and FF mothers were more active. Moreover, females rejected more aggressively and earlier their female chicks than their male chicks. Finally, Mx chicks, whatever their sex, interacted more with their mothers. Our results highlight a greater quantity and quality of maternal care towards male. Mothers invest more in male chicks. We discussed results in terms of each sex's needs.

“…The thorn-tailed rayadito (Furnariidae: Passeriformes) is a small (~11 g) endemic insectivorous species residing in temperate forests in Argentina and Chile (Remsen 2003). The species is socially monogamous; both members of the pair contribute to nest building, incubation and the feeding of nestlings (Moreno et al 2007, Espíndola-Hernández et al 2017). Females lay one clutch per breeding season, during the austral spring, from October to December (Moreno et al 2005).…”

Age‐specific variation in reproductive effort can affect population dynamics, and is a key component of the evolution of reproductive tactics. Late‐life declines are a typical feature of variation in reproduction. However, the cause of these declines, and thus their implications for the evolution of life‐history tactics, may differ. Some prior studies have shown late‐life reproductive declines to be tied to chronological age, whereas other studies have found declines associated with terminal reproduction irrespective of chronological age. We investigated the extent to which declines in late life reproduction are related to chronological age, terminal reproductive attempt or a combination of both in the thorn‐tailed rayadito Aphrastura spinicauda, a small passerine bird that inhabits the temperate forest of South America. To this end we used long‐term data (10 years) obtained on reproductive success (laying date, clutch size and nestling weight) of females in a Chilean population. Neither chronological age nor terminal reproductive attempt explained variation in clutch size or nestling weight, however we observed that during the terminal reproductive attempt older females tended to lay later in the breeding season and younger females laid early in the breeding season, but this was not the case when the reproductive attempt was not the last. These results suggests that both age‐dependent and age‐independent effects influence reproductive output and therefore that the combined effects of age and physiological condition may be more relevant than previously thought.
