Birding with the Mulder family

A couple a months back I got a call from my friends Ico Jalink and Caroline Jalink-Mulder. They explained how they wanted to organize a surprise birding excursion for Caroline’s dad, Hans. Caroline’s parents live in Glimmen, just south of Groningen. As luck happens to be this is just a stone’s throw away from one of the best birding sites in the Netherlands; the Kropswolderbuitenpolder. I opted to plan the excursion somewhere late May a this is exactly the time of the year when a couple of very special birds can be found in this particular area….


May 31, 2015: 06:00 AM sharp.

I picked up Hans, Ella, Ico, Caroline, Inge, Wouter, Pieter and Olivia and we set of to our first location, which was just a 5 minutes drive away. Here, around an oak-fringed lawn, the world’s most northwestern breeding pair of Middle-spotted Woodpecker (Middelste bonte specht) make their home! However these retiring birds are very difficult to see this time of the year as the trees are covered in lush green. I told the group to be very quiet as we stepped out of the van….



On the lookout for Middle Spotted Woodpecker


After half an hour of waiting we had nearly given up, but a Spotted Flycatcher (Grauwe vliegenvanger), delivering its wonderfully simplistic song from an exposed perch, urged us to stay for just a little longer. Suddenly a small woodpecker zipped overhead and started foraging in the canopy 30 meters away from us; a male Middle Spotted Woodpecker! Pfew!


With this difficult species in the bag we headed for the Kropswolderbuitenpolder. Halfway there a male Bullfinch (Goudvink) perched in the middle of the road, always a great bird to see!


We took coffee and snacks with us to what must be one of the best lookout-point in the Netherlands. Here the roof of a concrete pumping station overlooks the Kropswolderbuitenpolder; a huge area covered in swamp, wet grassland and stretches of open water.



Hans, looking at Black-winged Stilt


It didn’t take long before we located one of the key species here: Black-winged Stilt (Steltkluut). We observed a female on the nest and a male foraging nearby.


It was a cloudy and windy morning, but thanks to the coffee and cake we were able to withstand the cold. A Common Snipe (Watersnip) displayed overhead. Ringed Plovers (bontbekplevier), Garganeys (Zomertaling), Spoonbills (Lepelaar) and a host of other species highly dependent on these wet grasslands were observed over the next two hours. Best of the bunch were a couple of Whiskered Terns (Witwangstern) and White-winged Black Terns (Witvleugelstern) foraging among Black Terns (Zwarte stern) in the distance. Luck was with us as one Whiskered Tern decided to forage above a small stretch of open water right under our noses. It even caught a frog and devoured the amphibian on a mud-flat just 40 meters away! Very cool indeed!



Look! Whiskered Tern!

Happy customers, happy guide!


After these successes in the Kropswolderbuitenpolder we headed for the Carel Coenraad- and the Breebaartpolder. Here we had one important target: Montagu’s Harrier (Grauwe kiekendief), one of the Netherland’s most iconic breeding birds. Half way there we had a sanitary stop which resulted in a perched Peregrine Falcon (Slechtvalk), the fastest bird on earth!


Upon arrival in the Carel Coenraadpolder we quickly found a male Montagu’s Harrier. Exceptionally beautiful birds indeed. Over the course of the next hour we found 4 more birds. A male Hen Harrier (Blauwe Kiekendief) with a mouse in its talons was a great bonus!


In the observation hut in the Breebaartpolder we observed a fine selection of waders from up close and practiced our ‘Grunnings’ with a local bird enthusiast. Soon after it started to drizzle so we drove back to Glimmen for a well deserved lunch…




Happy birding!
