Standing at the brink of a very busy period of work, I made the most of the last few days to get some memorable wildlife encounters.
A few replies ago I wrote about the adder being my most wanted species in the Netherlands. The second most wanted species at the time was a spectacular diurnal moth called a tau emperor. So after a saw an adder a few weeks ago, the tau emperor became my number one target species. I kept that place for, well, only a few weeks, because last weekend I succeed in seeing not one, not two, not five, but about ten individuals! The new top target now is probably a toss up between smooth snake, common spadefoot, broad-boarded bee hawk moth (what a name!) and alcon blue.
The search for tau emperor is barely worth describing. With the same friend that accompanied me on the adder search, we walked a few hours in a forest that supposedly was tau emperor habitat. Seeing the moths was super easy, barely an inconvenience. They were just flying around like it's a completely normal thing. Turns out being at the right place at the right time of year with reasonable weather conditions is enough to see them. They are a spectacular sight though, so I thoroughly enjoyed myself.
The other additions are from various other trips (including some bat surveys for work), the largest one was a full-day excursion to the Biesbosch. Besides spring marshland birds our main target was sand-coloured carder bee, a highly threatened species in the Netherlands that should be rather easy at that location. Despite only brief periods of sun in between the rain showers, we managed to see several individuals foraging among the comfrey and white nettles. There were also plenty of warblers in many species around, no less than eight species of gull and three juvenile white-tailed eagles. I also saw my first (identifiable) dragonflies and grasshoppers for the year.
