Lee & Holyoak (2017) focused on Lesson as a source that we had neglected in our discussion of Chattering Kingfisher Todiramphus tutus on Tahiti. They are apparently confident in the accuracy of specimen labels from Lesson's era despite that the labelling of even Lesson's own specimens is poor. Based on meticulous notes taken during the Whitney South Sea Expedition by Beck and Quayle in the early 1920s, as well as their specimen material, we demonstrate that they never collected T. tutus on Tahiti, where they collected only Society (Tahitian) Kingfisher T. veneratus. Lee & Holyoak's suggestion that both species occurred in the Society Islands but became extinct in either the western Leeward Islands (veneratus) or eastern Windward Islands (tutus) seems to be a case of selective extinction following an established biogeographical divide. We believe that the observed pattern is best explained by the fact that veneratus was never present on the Leeward Islands and tutus never occurred on Tahiti: this represents the most parsimonious interpretation of the available data.

We re-examined the putative type specimen of Society Kingfisher Todiramphus veneratus (J. F. Gmelin, 1788) in the Naturhistorisches Museum Wien (NMW 50.633) and conclude based on plumage that it represents the taxon from Moorea, T. veneratus youngi Sharpe, 1892, rather than nominate T. veneratus veneratus from Tahiti. X-rays reveal that it was prepared using techniques common in the late 18th century, and that its preparation style matches that of other specimens collected during Cook’s three voyages. NMW 50.633 has been assumed to be the one, or one of a number of, specimen(s) used by Latham to describe and illustrate his ‘Venerated Kingfisher’ (present-day Society Kingfisher), which was the basis of the later valid introduction of the name Alcedo venerata by J. F. Gmelin. However, whereas the description and an unpublished illustration in Latham’s archives agree closely with veneratus from Tahiti, NMW 50.633 appears to represent Moorea youngi. While this finding does not compromise the definition of Society Kingfisher veneratus, it leaves it without a safely identified type specimen. We also examined a Moorea specimen in the National Museums Liverpool (LIVCM D2366) that is almost as old as NMW 50.633, but which X-rays suggest had a different origin than NMW 50.633.

We examined the occurrence of six species of meadow birds (four wader species and two songbird species) in relation to the distance to the nest location of an avian predator (three species). We related our findings to the degree of openness of the landscape in which this avian predator nest was located. The degree of openness varied from very open to very closed, depending on the number of view-obstructing landscape elements in the landscape (none or very few in open ones, but completely covered with forest or built-up area in very closed landscapes). We used a dataset containing nesting locations of meadow birds and predators in the province of Gelderland, the Netherlands, allowing us to perform the analysis on three grid cell sizes (100×100 m, 250×250 m and 500×500 m). Our results show that, for each grid cell size, all meadow bird species showed highest nesting densities in open landscapes. Lowered densities were found around occupied nests of avian predators, irrespective whether the predator's nest was situated in an open or closed landscape. The preference of meadow birds for open landscapes away from predator's nests suggests that a large visibility, that allows them to scan for predators to be able to chase them away in time, is an important habitat requirement for meadow birds to select a nest site. It also suggests that openness of the landscape, independent from the presence of occupied predator's nests, is a factor in selecting a nest site. In contrast, for two out of three species of avian predator, we found that they chose more closed landscapes to nest because these species nest in landscape elements like wood lots and lone trees which make the landscape more closed by definition. For the third avian predator species, the grid cell size was probably too small to find a consistent result, as that species has territories larger than even the largest grid cell size we used.
