Birdwatching in Tokyo: Ueno Pond
Shinobazu-ike is a large pond of Ueno-park adjacent to
Ueno Zoo in the centre of Tokyo. In the middle of the city it is a
rather unexpected refuge for wintering birds. In summer season it is quiet.
The water is a bit
drab and dirty, perhaps due to a high density of birds, the food that people feed
the birds and all the garbage one can possibly encounter in a park. Shinobazu-ike is a lotus pond. Birds can hide between the tall stems of the lotus leaves. In winter time the partly broken stems carrying brown leaves or seedboxes remain in the centre of the pond. The sight of all hundreds of pintails begging for
food, while swimming or walking close to you is unbelievable. They
turn out to be quite noisy on close range: "easy, easy, easy..."
Usually my visits are brief and hurried: "passing by" visits only. The list below just gives an impression of the sorts. One can encounter funny species: I have seen there a male (hybrid ?) Baikal Teal, a partially albino female pochard (known by the local homeless as the destroyer), a male Ring-necked Duck and a female Baer's Pochard.

Place: In the SE corner of the pond at three meter distance of the sidewalk. One week later it was still there, and photographed by Stephan Shuichi Haupt. It turned out to be ringed, so perhaps an escape bird from the zoo.
Description: The general distant impression of the small
teallike duck was darkish with two pairs of big dirty white spots on
both sides of the bill. On close distance (4 meter) the yellow, dark
green and black facial pattern as depicted in the field guide revealed
itself. Crown of the head was darkgreen fluorescent, sometimes
appearing dark purple. Underlining the crown was a white eyeline over
and around the yellow spots and the green ear coverts: together these lines formed a white
'V' on the nape. The breast was
chestnut colored with black dots, the side greyish. Under tail coverts
were black. Between the grey flank and the black under tail coverts
there was a clear vertical white line.
However, the white line between the buf breast and the grey flank
however was LACKING! (Neither was the white underlining of the yellow
spots and the green ear coverts present, as visible in the guides or at this beautiful picture of another Baikal teal by Koike-san.)
I did not see the wing-pattern, as the bird was swimming quietly only, and after some
minutes swam into hiding between the died lotusplants which fill Ueno pond.
The bird had no markings reminiscent of Wigeon, Teal or Pintail, I believed at first.
However study of the photographs of Shuichi Haupt suggests a hybrid between Pintail and Baikal teal.
Afterthought: the new book "Wild birds in Japan" contains a picture of (as the caption says) hybrid Baikal Teal x Pintail. The bird of the photo in the book is strikingly similar with the bird on Shuichi Haupt's photographs, including the detail of being ringed with an old metal ring on one leg... (whether or not it is the same leg, I don't know, not having seen the original negatives of both the photos of Shuichi Haupt and the photo in the book!?)

Partial albino Pochard (?)
: B, H, I, J, K
It seems me the same bird on all visits. One homeless person told me that the bird is already since 7 years a winter visitor (this might imply that he is living as a homeless for at least 7 years in Ueno...). The nickname among the homeless for bird is the destroyer. I am not sure which species it is: perhaps a female pochard
- Baer's Pochard
Aythya baeri Aka-hajiro: J one female.
Description of the swimming duck between the Tufted ducks: Size in between Pochard and Tufted duck.
Head: brownish black with lighter brown patches near bill (hard to see at distance) Dark eye. Bill: dark grey with a light greyish band near tip. Neck blackish brown. Breast dark brown. Mantle like female Tufted Duck. Flank however more brownish mottled and along the waterline more whitish between the middle of the duck and the back of its neck. Tail spread like a small fan and held above the water, in contrast to usual posture of the female tufted ducks. Neck was elegant long and relatively slender compared with the Tufted ducks.. Posture of neck sometimes reminding of gracefully curved neck of Mute swan. So far this seems to be a description fitting a usual femal Baer's pochard. However this individual had a partial white collar on the breast! In frontal view resembling a the colar of male Mallard with respect to position and width of collar.
Behavior: It allowed itself to be fed by the homeless of Ueno-park. At quiet moments times it came within arm reach of the side of the pond. When a piece of bread was thrown towards the duck, it wrestled with the tufted ducks to get it, but unlike the tufted ducks it escaped the whirlpole of struggling ducks via a long dive to the quiet lotus beds.
Conclusion: Female Baer's Pochard
