The sightings and occasional thoughts of an English birder in Oslo

Water Rail fest
I have previously mentioned the Water Rails that are
wintering at Østensjøvannet but haven’t gone into too much detail as I didn't want to give them too much attention. They have however now become very popular amongst photographers (in time honoured fashion as soon as one person posts a good picture on Facebook then many others want to take their own version) so I may as well publish this post. The
prolonged very cold conditions are undoubtedly hard for this species but the
very small stretch of a tiny stream that never freezes over seems to provide
enough food although extra food (oats and seeds) that are tossed out by birders and
photographers is probably a vital addition to their diet. Before it got too cold
and the birds could find food in the adjoining reedbed it seems that one bird was
quite territorial but when everywhere else froze over upto three birds have used
the stream and then there seems to be far fewer territorial squabbles. I assume this is because the
birds will rather use their limited energy to find food (I recently saw a
video of a territorial struggle between Water Rails that resulted
in one killing the other).
Of the three birds one is an adult whilst the two
others are first winter birds. The adult is dark grey on its cheek and throat
whereas the 1st winter birds have brown within the grey and a pale
chin. The eye colour of the adult also seems to be a darker red although I am
not sure whether this is due to different light when I took the photos of the
individual birds. This photo compares the three birds.
One of the 1st winter birds had a damaged
leg on the day I took these pictures and video (28 January) and was clearly in
a poor state of health. It spent most of its time standing still and was very
puffed up whereas as the other birds were actively feeding (a necessity at this
time of the year) and looked much sleeker. The cause of the injury is most
likely from an uncollared black cat that I saw in the area on most occasions I
have visited and twice it was clearly stalking the rails and lunged for them. (the injured bird was not as far as I know seen again after this day).
