Bird Taxonomy and Photo Album Collections

There are about 10,000 known species and 22,000 subspecies of birds in the world, and to-date I have only photographed a modest 500 species. However, taking sexual dimorphism, different subspecies, age, habitat, and behaviour into account, I have significantly more images of interest.

Aves (Bird) Taxonomy

Choosing one of the many bird taxonomies and associated checklist to follow depends in part on the aims, location of the authority and personal requirements. There are four primary checklists for birds of the world: Clements, Howard & Moore, HBW Alive/Birdlife, and IOC World Bird Name. There are others, such as Sibley & Monroe.

I decided to follow HBW Alive because:

(a) It offers online access to HBW and BirdLife International Illustrated Checklist of the Birds of the World, published by Lynx Edicions;
(b)  BirdLife International is ‘The International Union for Conservation of Nature’ (IUCN) Red List Authority for birds;
(c) And I have full access to HBW Alive on an annual subscription basis and to ‘My Birding’ database allowing me to record sightings and birding trips.

Note: The Handbook of the Birds of the World (HBW Alive) content has transitioned from Lynx Edicions (Lynx) to the Cornell Lab of Ornithology. HBW Alive will become the backbone of the new Cornell Labs ‘Birds of the World’ in early 2020. The Cornell Lab of Ornithology houses the eBird database and associated birding tools together with the Macaulay Library, which will also hose the Internet Bird Collection (IBC). Currently, I don’t know how the change from HBW/BirdLife checklist to Clements affects my records. Similarly, how the shift from HBW ‘My Birding’ to eBird will impact my bird records.

Photo Album and Collections

My bird image names are consistent with common and scientific names given in the HBW Alive / Birdlife checklist. However, the arrangement of families, genera and species into higher-level taxonomic groups is complicated with several completing classification systems. I’ve arranged my photo albums in six collections

The first four cover passerines based on taxonomy:

(a) Basal Oscines;
(b) Passerida;
(c) Corvida;
(d) Suboscines.

The last three cover Non-passerine based on habitat:

(a) Landbirds;
(b) Core Waterbirds;
(c) Waterbirds (including waders);
(d) Seabirds (including pelagic).

For each collection of photo albums, a webpage introduces them and provides hypertext links to second level webpages that display image galleries of related bird families. The galleries feature portraits of each species that I’ve photographed. Also, an additional gallery that highlights behavioural or environmental themes; such as nesting, hunting, feeding, habitat, action, or my favourite images.

Passerines

Passerines are birds in order Passeriformes, which is the largest and most diverse bird group. Under Sibley and Ahlquist (S&A) Taxonomy, Passeriformes splits into two suborders:  Tyranni (Suboscines) and Passeri (Oscines). Passeri then splits into two parvorders Corvida and Passerida parvorders. However, more recent studies using the modern approach to avian taxonomy using DNA sequences and analytical methods have shown that S&A taxonomy is complicated. Proposed taxonomic changes are frequent with only some of the less controversial ones accepted by some authorities. To help the presentation of my photo album, I follow J Boyd’s Taxonomy in Flux Checklist, and to some extent IOC World Bird List, Order of Birds. I use both these for reference when understanding taxonomic changes and proposals to Aves orders and families.

The primary difference between S&A and J Boyd Checklist for passerines is the split them into three suborders: Acanthisitti (New Zealand Wrens), Tyranni (Suboscines) and Passeri (Oscines). Also, the introduction of Basal Oscines, the latter is split from Corvida into several new parvorders and new superfamilies.

Oscines distribution has a worldwide with about 40% of known species. Often but less accurately called songbirds, these birds have highly developed voice boxes. Suboscines has about 10% of known species; these have simple voice boxes with a pan-tropical distribution. And New Zealand Wrens has four known species.

Passerines or perching birds, so-called because of their toe arrangement, three toes forward and one backward allowing them to grip a perch. They are vocal, small to medium size, brightly coloured birds that need to care for their chicks before they can fledge.

Non-Passerines

Non-passerines refer to the other 50% or so of birds species, that placed in separate Avian orders. Authorities disagree as to the number of species and their placement in families and orders.

HBW Alive recognises 35 orders and 105 families of non-passerine although this is subject to update when they accept change. I follow J Boyd’s Taxonomy in Flux Checklist, which currently lists 46 orders, including Passeriformes and 248 families. I have adopted most taxonomic changes to the Aves orders and families in J Boyd’s Taxonomy in Flux Checklist. I also check differences with the IOC World Bird List, Order of Birds.

The species list in both passerines and non-passerine is constant, give or take a hundred or so. But their placement in families and orders is ever-changing as is sub-species, common names and with the discovery of new species and subspecies.
