Alcedophaps
Phylum: Chordata
Class: Aves
Order: Columbiformes
Family: Columbidae
Subfamily: Columbinae
Genus: Alcedophaps
Species:
A. alcedo : Blue-hearted Kingfisher-dove
A. nigrifrons : Turquoise Kingfisher-dove
A. laetus : Splendid Kingfisher-dove
Blue-hearted Kingfisher-dove
Alcedophaps alcedo
Diet: Seeds, nuts, berries, supplemented with invertebrates
Size: 11 cm
Lifespan: 7 years
Group size: Pair
Habitat: Montane Cloud Forest
Behaviour: Exclusively found within a few metres of the cauliflorous (trunk flowered) and ramiflorous (branch flowered) tree Cyanoperuiflora crinitus of the family Operuifloracea. The plant is covered in large, bright blue flowers on its trunk and leaves creating a flower coating 15 centimetres thick. The birds live near it for camouflage of its nest and when it forages in the surrounding ground, covered in blue flowers.
Due to its small size, it can make a nest concealed in the flowers, and eats the bright blue fruit. This also makes it highly dependant on this tree species in an elaborate symbiosis, as its droppings fertilize the tree, and can accidentally pollinate the plant.
Occasionally moves a few metres away from the grove, to make it much more obvious to mates or competitors or to analyze the environment for dangers.
It is extremely scaredy and super easy to provoke, and immediately darts for the grove of trees it chose to inhabit.
2 weeks incubation
3-4 eggs per clutch, throughout the year but peaking in summertime
Female incubates as it is much darker and more similar to the colour of the tree, while the male is brighter than the flowers to grab the attention of females.
Threats: Deforestation, plant disease (which luckily hasn’t happened yet), invasive snakes
Status: Critically Endangered, due to the fragile symbiosis it has formed
Turquoise Kingfisher-dove
Alcedophaps nigrifrons
Diet: Seeds, nuts, berries, supplemented with invertebrates
Size: 12.5 cm
Lifespan: 6 years
Group size: Pair
Habitat: Montane Cloud Forest
Behaviour: Exclusively found within a few metres of the cauliflorous (trunk flowered) and ramiflorous (branch flowered) tree Cyanoperuiflora fuscus of the family Operuifloracea. The plant is covered in large, darkish blue flowers on its trunk and leaves creating a flower coating 14 centimetres thick. The birds live near it for camouflage of its nest and when it forages in the surrounding ground, covered in blue flowers. This is almost identical behaviour to A. alcedo but the colouration of this species’ host is darker, much like their own colouration.
Due to its small size, it can make a nest concealed in the flowers, and eats the bright blue fruit. This also makes it highly dependant on this tree species in an elaborate symbiosis, as its droppings fertilize the tree, and can accidentally pollinate the plant.
Occasionally moves a few metres away from the grove, to make it much more obvious to mates or competitors or to analyze the environment for dangers.
It is extremely scaredy and super easy to provoke, and immediately darts for the grove of trees it chose to inhabit. Much braver than A. alcedo, though

Threats: Deforestation, plant disease (which luckily hasn’t happened yet), invasive snakes
Status: Endangered, due to the fragile symbiosis it has formed, but it is much more likely to survive such a disaster than A. alcedo
Splendid Kingfisher-dove
Alcedophaps laetus
Synonyms: Papiliopelia laetus
Diet: Seeds, nuts, berries, supplemented with invertebrates
Size: 10 cm
Lifespan: 4 years
Group size: Pair
Habitat: Montane Cloud Forest
Behaviour: When in danger it tucks its beak into its neck, and opens its wings and flaps it. It has evolved as a batesian mimic of the highly toxic Nymphalid butterfly Paramycalesis elegans.
It is easily provokable but only in reasonably dangerous situations will it panic and fly off.
2 weeks incubation
3-4 eggs per clutch, throughout the year but peaking in summertime
Females are far duller and thus incubate the eggs
Threats: Deforestation, invasive predators who lack the experience of eating the butterfly it mimics
Status: Endangered
Remarks: Its differences from the rest of its genus led scientists to place it in its own monotypic genus, Papiliopelia, but recent molecular studies confirm its placement among Alcedophaps.
It coincidentally resembles the Ceyx kingfishers.
