How to describe a bird accurately Objectives of the module At the end of this module you will be able to: • name the different parts of a bird’s body; • describe the shape of a bird; • describe a bird’s plumage; • describe a bird’s behaviour.
How to describe a bird accurately Approach Identifying a species = rigorous description • Note all key elements needed for a description • Describe the bird objectively • Write down the description • before the bird flies away • before looking at the field guide
Shape Size • Compare size to that of a well-known bird • for example: “bigger than a turtle-dove but smaller than a whistling duck”
Shape • Silhouette • often characteristic of a family or genus • Round: plovers • Elongated or slim: stilt, Tringa sandpiper, egret • Hunched or stocky: Squacco Heron at rest • Remember that general shape can change with the bird’s posture.
Shape Neck length • short: plovers • medium: ducks • long: Tringa sandpipers, herons, storks position in flight • extended: storks, Anatidae, flamingos • retracted: herons, pelicans
Shape Shape of the bill • pointed and dagger-shaped for fish-eatingbirds: herons, kingfishers • flat: ducks, spoonbills • slender and long: birdsthatfeed over mud: waders - straight: snipes - downcurved : curlews - upturned: avocet • short: plovers, gulls, crakes
Shape Length of the bill • Short or long • Compare with length of the head seen from the side Bill > head Bill = head Bill < head
Shape • Toes … if they are visible • webbed: ducks, geese ... • not webbed: waders ... • very long: jacanas…
Shape • Legs • long: extending beyond the tail when in flight, or clearly visible tibia when on the ground: large wading birds, Tringa sandpipers, Godwits, etc • short : do not extend beyond the tail when in flight, or the tibia is hardly visible when on the ground: Anatidae, cormorants, grebes, Calidris sandpipers, etc. Not extending beyond the tail Legs in flight Extending beyond the tail tibia tarsus clearly visible Tibias hardly visible
Shape Wings in flight length • long • short shape • broad: storks, herons, pelicans… • pointed: terns, Tringa sandpipers ... • rounded : rails...
Shape • Tail • length • long: African Darter • short : teal, Little Grebe • shape • rounded: Common Snipe • forked, v-shaped: pratincoles, terns • pointed: Jack Snipe, Collared Pratincole

Colour and contrast • Different shades of the same colour: • light grey ... dark grey speckled grey ... stripy grey
Colour and contrast • Shades of mixed colours: • … grey-green … grey-brown … reddish-brown …
Colour and contrast • Vague terms • whitish ... reddish ... greenish
Colour and contrast • Colours will look different in different lights
Colour and contrast • How colour and size are perceived varies with the background against which they are seen Birds can seem smaller than they really are against a light background
Colour and contrast • To make a good description it is important to describe • plumage: patterns, colours and contrasts of each part • colour of the legs • colour of the bill • colour of the bare skin and wattle for some species, etc.
