Last time that I blogged here about a boat in Naardermeer nature reserve, it was in fall. Now, it was in spring.
Also, last time, the boat started in the north west of the lake. This day was the first time ever that the boat started from the east.
Before the boat started, cuckoo sounds. A great cormorant. A speckled wood butterfly. A kestrel, hovering.
The canal to the lake where we started, has been dug recently. During the digging, several archaeological discoveries were made, including old pipes from Gouda, and canonballs from the many times when there had been sieges of nearby Naarden town.
There are many damselflies above the water. This time of the year is mating season, especially for blue-tailed damselflies and large red damselflies. Many of them in love tandems. Especially large red tandems sit down on the boat. Hundreds of blue-tailed damselflies, most of them in tandems, are close to the water.
A great crested grebe.
Then, we go to the great cormorant nesting colony. A few decades ago, five thousand couples used to nest there. That was 90% of all great cormorants of the Netherlands. Since then, the species has increased in the Netherlands as a whole, while decreasing in the Naardermeer. Today, 1000 couples nest here, 5% of the national total number. This is because there are now good nesting opportunities in Flevoland province nearby. In some great cormorant nests here, there are already chicks, in other nests not yet.
Willow warbler and chiffchaff sounds.
A buzzard in a tree.
On a bank grow lots of carnivorous plants. They are common sundew. A blue-tailed damselfly is caught by one of them.
A young edible frog hops past.
A pied wagtail on a small bridge.
Stratiotes, still underwater at this time of the year. This species is important for at least two animal species: black terns who nest on it; and Aeschna viridis dragonflies who lay their eggs on them. Someone sees a downy emerald dragonfly.
The song of the Savi’s warbler.
A grey lag goose. A common sandpiper.
A gadwall duck.
Just before the boat gets back to the beginning, little ringed plovers.
As we walk back, a blackcap in a tree.
We go to the west side of the Naardermeer.
Redshanks. Gadwalls and shelducks. A common tern, diving. Reed bunting sound. A sedge warbler in song flight.
Three lapwings driving a carrion crow away.
In a meadow: grey lag geese, escaped domestic geese, barnacle geese, and a Canada goose.
A white stork passed, flying very close to the bicycle track.
Then, two Egyptian geese, flying.
