This is a list of Columbiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. ... Tooth-billed pigeon ...
A related extinct species, the Tongan tooth-billed pigeon (Didunculus placopedetes), is only known from subfossil remains in several archeological sites in Tonga. [2] [3] The tooth-billed pigeon is the national bird of Samoa and featured on the 20 tālā bills and the 50 sene pieces of the 2008/2011 series. Native only to Samoa's primary ...
The Tongan tooth-billed pigeon (Didunculus placopedetes bebefolis) is only known from subfossil [4] remains in several archaeological sites in Tonga dating 2700–2850 BP [5] and now extinct. The tooth-billed pigeon ( Didunculus strigirostris ) from Samoa is critically endangered .
The average global population of all mature birds is estimated to be on the order of 100 billion individuals. [1] [2] [3] The total population including younglings is somewhat higher during the breeding season of each species. [3] This list is incomplete, because experts have not estimated all bird numbers.
Additionally 55 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 3 ]
The Tongan tooth-billed pigeon is described as looking similar to its relative, the tooth-billed pigeon, although it was larger. The Tongan tooth-billed pigeon is only defined by subfossils found at archaeological sites. A common predator of the Tongan tooth-billed pigeon was the barn owl (formerly T. a. lulu; now T. j. delicatula).
Estimate is for mature individuals. This comes from a count in 2000 of 2,244-2,610 individuals on Mauritius, with population on Reunion thought to be larger. Difficult to quantify population trend, as some populations have increased and others have decreased. An overall decrease due to habitat loss is assumed. [42] Mexican woodnymph: Eupherusa ...
