Before today there had not been too much since I
last posted but the first Green Sandpiper turned up on Thursday and diver
numbers have increased to 3 Red-throated and 4 Black-throated on the lake. The
pair of Buzzards has been displaying and I have hopes of finding their nest
this year for the first time. There are at least 7 Whooper Swans and a pair of
Mute Swans in the valley and it will as usual be interesting to see who manages
to breed and how much fighting there will be.
Yesterday’s undoubted highlight was provided by the
Three-toed Woodpeckers. I had a full-on territorial dispute between 2 pairs
whilst a seemingly unpaired male was drumming less than 200m away. The
territorial dispute reminded me of last years fighting between 2 females but
this time the male(s) were also fully involved. Most of the time the two
females were having a standoff on one tree and the males were doing the same on
another but occasionally all 4 were on the same tree. Whilst they were fighting
there was no drumming but they had been drumming from separate areas when I first
arrived. One-toe was one of the females and it is tempting to believe that the
other female was the victorious bird from last year. As for the males then I
have no idea who they were. Today I only found one pair which was one-toe and
her mate so they seem to have won the battle but have they won the war.
Today ended up being an OK day. It started quietly
in the Dale and I decided to decamp to Fornebu. There wasn’t much there but I
did see my first Ringed Plover, Wheatear and Moorhen of the year plus three Slavonian
Grebes offshore. There were 10 Ringed Plovers displaying in the middle of a
building site that was quiet due to the Easter holiday. I don’t know how they
will fare next week.
A dog walk in the afternoon in Maridalen revealed my
first Osprey of the year so four new species for the year in one day must mean it was an OK day.

then a male turns up which was the mate of three-toe |

and the other male is on his way to join them |
all 4 together. One of the males is at the top and the other is in the middle of the two females |

the females are really fighting and it is One-toe who seems to have the upperhand |

Ringed Plovers (sandlo) at Fornebu |
Wheatear (steinskvett) also at Fornebu |

I previously also mentioned how we observed courting
and mating Canada Geese. Thi was actually very cool to observe. The pair swam
side by side and at first I thought they were bathing but then realized it was
going on too long and was ritualized. They would put their heads and necks and
forebodies underwater and when they came up water would rush over the rest of
their bodies. This went on for a period before the male grabbed the female by
the neck and then mounted her. She was forced underwater and it went on for
quite a few seconds before she seemed to roll and push the male off. He then
carried on holding her by the neck and maybe wanted to go again before letting
go when they then both held themselves very proud and erect and called before
both preened and cleaned themselves before flapping their wings.
here they are having some foreplay - the female on the left is smaller |
notice all the water on the body |
a first for me - the penis of the male |
here the female is bathing after the act |
and shaking the wings in triumph? |
It looks like Google has censored all my pictures of the Canada Geese perhaps because I used some "saucy" words. I'll post the pictures again without text and see if they survive the Big Brother surveillance
