SWANS AND GEESE

Placing the mouse pointer over an image will produce arrows letting you navigate this slideshow manually.

The Mute Swan is the commonest swan and the only one in Britain likely to be seen during spring and summer. It is graceful and usually silent, but can hiss or snort. The difference between male and female is not always obvious. During the breeding season the black knob at the base of the male's bill swells to become noticeably larger than that on the female. The Pen (female) incubates her eggs on a heap of vegetation while the Cob (male) keeps close guard against predators and chases them off. Both adults share the responsibility of caring for the nest. Once cygnets are old enough to look after themselves the parents loosen the parental ties. If the cygnets are reluctant to leave the parents may chase them away rather aggressively. Swans feed on water plants, seed, snails and insects.


Barnacle Geese are infrequent visitors to Hainault Lake, usually in small groups and not staying for long. The face is white and the head and neck black. The belly is white and there are grey bars on the back. During summer the geese breed in the Arctic. They feed on grass, other vegetation and seeds.


Canada Geese were originally introduced from North America and are now well-established in Britain. Their goslings are capable of walking, swimming, and finding their own food immediately after hatching. Parents often lead their young in a line, usually with one adult guarding the front and the other at the rear. Although parents can be hostile to unfamiliar geese they may form creches of goslings with adults they know. Goslings often stay with their parents for their first year. Canada geese feed on grass and are attracted to mown areas because it gives them a clear view of any approaching predators. They have a tendency to move away from locations where grass has been allowed to grow longer. 


The Greylag Goose is the ancestor of most domestic geese. It has a brownish-grey body, pink legs, an orange bill and is the largest and bulkiest of British wild geese. Greylags feed on grass, other vegetation and seeds.


Egyptian Geese are brown and grey with dark brown eye-patches. They were introduced to Britain as an ornamental species, some escaped into the wild and are now successfully breeding in the wild. They usually pair for life. The male attracts a mate with an elaborate courtship display that incorporates honking, neck stretching and feather displays. These are "Geese" in name only. They are actually a type of shelduck -- an intermediate species somewhere between geese and ducks. As far back as 3100 B.C. the Ancient Egyptians kept Egyptian Geese as pets making them one of the oldest domesticated species. They are now the most widespread African waterfowl appearing in many countries around the world after being introduced.

Two visiting swans had been ringed (see slideshow) as part of a long term study investigating the demography of Mute Swans in south east England.

4CBX (Ring No. W41764) was a 6-year-old Pen(female), ringed by Mike Reed in 2016. She was spotted at Hollow Pond, Whipps Cross a number of times during 2016, 2017 and 2018. The last known sighting was at Wanstead Flats on 22nd April 2018.

4BXZ (Ring No. W41470) was a 5-year-old Pen, ringed by Mike Reed in 2016, also a regular at Hollow Pond, Whipps Cross during 2016 and 2017. Sadly, she was reported dead there after an animal attack on 1st November 2017.
