Today I was guiding the grandfather of one of Jr Jr friends
as a 75th birthday present. I chose Østensjøvannet as the perfect
place and we used nearly 3 hours here in perfect spring weather. The woodland
around the lake was heaving with singing Willow Warblers which were easy to see
as the leaves have yet to come out and Blackcaps were also back in force but it
was still too early for many of the other warblers.
The lake was also alive with birds. I didn’t make any
attempt to count the Black-headed Gulls but I would guess there are way over
500 pairs. The gull colony provides protection and encourages other birds. At
least 7 Canada Geese were on nests but I believe all eggs have been pricked
which may explain why a lot of the birds kept leaving their nests and looking
confused. There were 3 Mute Swan nests but at least 13 adults on the lake with
frequent skirmishes. One fight involved two males swimming side by side for a
few minutes with wings raised before one viciously attacked the other by grabbing
its neck and trying to push him under water. Both birds survived the event but
one lost a lot feathers. Great Crested Grebes were also nesting with four nests
seen and over 20 adults around the lake with some still displaying- There were
many Tufted Ducks which are late nesters and have begun nesting yet. A pair of
Wigeon were most likely migrants but three Teal may well try to breed.
The wintering female Pintail was not to be seen but she was
seen not so long ago mating with a male Mallard so maybe she is on a nest and
will produce some interesting hybrid offspring?
Incredible news has just surfaced of a Kentish Plover photographed on the dried out mudbanks at Årnestangen on Monday and posted in a "what's this bird?" group. Given the size of the area it must be pure chance that the bird was seen and was close enough to a path. The bank holiday weekend will surely go down as one of the best weekends for rarities in these (rarity scarce) parts.
not the most photogenic Wryneck (vendehals) but always a pleasure to meet this species |
