SummaryThis paper attempts to verify the importance of spatial positioning of the eyes of reef heronsEgretta gularis schistacea, when coping with light refraction at the air-water interface. The herons' striking of prey, while their approach angle was restricted, was observed. (a) The herons' capture success in the restricted situation was markedly lower than in the unrestricted situation. (b) The points of strike (STR) in unsuccessful strikes differed from those of successful strikes, and from… 
Repeated evolution of drag reduction at the air–water interface in diving kingfishers
TLDR
Kingfishers are a well-known clade that contains both terrestrially foraging and plunge-diving species, allowing for morphological and performance differences between foraging guilds in an evolutionary context to indicate that the morphology between the beak and head is a key site for reducing drag in aquatic species.
Prey capture success of Sandwich Terns Sterna sandvicensis varies non-linearly with water transparency
TLDR
Diving terns in the south eastern North Sea are observed and a non-linear optimum curve for the relationship between Secchi transparency and prey capture probability is found, showing that Sandwich Terns adjust their diving technique in response to water transparency.
Adapting foraging to habitat heterogeneity and climate change: an individual-based model for wading birds
TLDR
Increased variance in precipitation regimes is more likely to affect tactile rather than visual foraging bird species, and in harsh climatic conditions (increased precipitation and water level regimes) solitary foraging was more beneficial for wading birds than group foraging.
Visual fields in the Black-crowned Night Heron Nycticorax nycticorax: nocturnality does not result in owl-like features
TLDR
The comparatively large size of the Black-crowned Night Herons' eyes may be associated with activity over a wide range of natural light levels but does not give rise to binocular fields larger than those of diurnal heron species.
La pêche de Ceryle rudis Linné, 1758 (Alcedinidae: Coraciiformes, Aves)
TLDR
It is found that Ceryle rudis is very active in fishing until midday and it is less so in the afternoon, and the average number of fish eaten per day per bird was 9,3.

Visual fields in herons (Ardeidae) — panoramic vision beneath the bill
TLDR
The interaction between Indonesian Myrmecina and the myrmecophilous oribatid mite is the first case of ant-myrmecophile relationships and comparative studies of the interactions are important.

TLDR
Archerfish (Toxotes chatareus) spit droplets of water at aerial insect prey, knocking them onto the water surface to be eaten, and can correct for large refraction effects on the prey's apparent elevation or apparent height.
