A bit off-topic, but the situation of wildlife in the Dutch countryside is complicated. In theory, the Netherlands can have (and used to have) a very rich and biodiverse countryside, with plenty of rare and interesting species including our national bird, the black-tailed godwit. In practice however, the vast majority of our agriculture is highly intensive and industrialized to the point where even barn swallows and starlings struggle to survive. Most of our agricultural land is an ecological desert, with very high nutrient levels but poor soil quality, large amounts of pesticides, unnatural hydrology and an almost complete absence of wildlife refuges. There is a reason the number of skylarks, once the most abundant breeding bird in our country and typically associated with farmland, has dropped by over 95% in the last decades. Why our country is this way is a topic for another time.
In contrast, the places where old practices have been conserved for historical/cultural purposes are often teeming with life. Those are some of the best birding spots in the country.
