“…As expected, significantly more chicks fledged in larger nests, which parallel other findings on passeriformes and little grebes. 38,47 In contrast, we were unable to find a significant effect of nest size on breeding success in moorhens and little grebes in the same study area. 43,48 This nest size-dependent breeding success likely varies between precocial and alticial chicks.…”

Understanding the factors that influence avian reproductive output is critical for bird conservation as they reveal key considerations that directly impact a species’ long term survival and should be integrated into management plans. To better this understanding for the little bittern Ixobrychus minutus, we investigated how their breeding success relates to breeding time, nest size, water depth, and egg size in a man-made wetland (Ab-bandan) during the 2008 breeding season in Mazandaran Province, northern Iran. For each nest, the dates of the first egg laying, the first hatching, and the first fledging were recorded as well as clutch sizes. Nest size parameters (height, depth, and diameter), water depth under the nest, and egg characteristics (shape index and weight) were measured. The first egg was laid on March 21 and the last chick left the nest on June 24. From 140 eggs in 25 nests, 127 eggs hatched (91%) and 121 fledglings left their nests (87%). Generalized linear modeling revealed that nest diameter positively affected breeding success ( p = 0.001) meaning larger nests were more likely to produce fledglings. Further studies will be necessary to elucidate the underlying mechanisms.

“…Podicipedidae (grebes) Grebes are diving birds that prefer shallow, open waters for feeding but require emergent vegetation for nesting (Athamnia et al, 2015). The least grebe (Tachybaptus ruficollis capensis), black-necked grebe (Podiceps nigricollis gurneyi), and great crested grebe (Podiceps cristatus) occur in Africa today.…”

Fossil bird data (community composition and taphonomic profiles) are used here to infer the environmental context of the Oldowan-Acheulean transitional period at Olduvai Gorge, Tanzania. This is the first comprehensive report on the Middle Bed II avifauna and includes fossils excavated by the Olduvai Geochronology and Archaeology Project (OGAP) and recently rediscovered fossils collected by Mary Leakey. Crane, ibis, darter, owl, raptor, crow, and vulture are reported from Bed II for the first time. The presence of these taxa, absent earlier in this Bed, point to a general opening and drying of the landscape with grassland and open woodland expansion. Taxa associated with dense, emergent wetland vegetation, such as dabbling ducks and rails, are uncommon and less diverse than earlier in Bed II. This suggests more mature wetlands with clearer waters. Cormorants continue to be common, but are less diverse. Cormorants and other roosting taxa provide evidence of trees in the area. Compared to lowermost Bed II, the Middle to Upper Bed II landscape is interpreted here as more open and drier (but not necessarily more arid), with matured wetlands, scattered trees, and a greater expansion of grasslands.

“…BP significa parejas reproductoras. on benthic invertebrates (insects, molluscs, crustaceans), amphibians, and small fishes that they capture mainly by diving (Cramp & Simmons, 1977;Ceccobelli & Battisti, 2010), which requires enough water availability (Athamnia et al, 2015). Diving ducks depict a similar response to changes in the NAO, also showing a significant Pearson's correlation with wetland flooded surface and with the NAO position, although weaker than in the case of grebes.…”

“…In the case of rails, although we found a strong negative direct effect of the NAO on rails breeding pairs, path analysis couldn´t find the indirect causes of this relationship. Maybe it is mediated by other variables not considered in this study, such as vegetation density, which could constitute a force driving nest-site selection for these waterbird groups (Battisti et al, 2006;Samraoui & Samraoui, 2007;Causarano & Battisti, 2009;Meniaia et al, 2014;Athamnia et al, 2015;Fouzari et al, 2018). Wetland vegetation, which is closely linked to water availability, protects from predators (Martin, 1995;Angelici et al, 2012) and could enhance reproductive success (Thomas et al, 1999;Samraoui & Samraoui, 2007;Meniaia et al, 2014).…”

Predicting how waterbird populations may respond to climate change is a major challenge for conservation, which could be addressed by understanding the effects of large-scale climate oscillations, such as the North Atlantic Oscillation (NAO), on breeding population size. Here, we explore the relationship between the NAO position and the abundance of waterbird breeding pairs in a protected Mediterranean coastal wetland (Mouth of the Guadalhorce River, Málaga, southern Iberian Peninsula). We found a significant and negative relationship between the winter NAO index and the abundance of grebes (r=-0.72, N=15, p<0.01), rails (r=-0.74, N=15, p<0.01), diving ducks (r=-0.56, N=15, p<0.05) and dabbling ducks (r=-0.54, N=15, p<0.05). Our results suggest that this relation is mediated by the NAO indirect effects on wetland flooded surface via changes in winter precipitation and Mediterranean sea level. These results should be considered to design appropriate environmental management strategies devoted to preventing or mitigating potential deleterious effects of the NAO variability on Mediterranean wetlands ecosystems and preserving their valuable waterbird communities.
