Grey wagtail named Bird of the Year 2025
The Czech Society for Ornithology has named the grey wagtail as the Bird of the Year for 2025. This decision aims to highlight the crucial role that natural waterways play in supporting this striking, long-tailed bird, as well as a variety of other wildlife, communities, and landscapes. To learn more about the Bird of the Year, I spoke with ornithologist Petr Voříšek.
I understand that the grey wagtail is a relatively common species in this region. What made you choose it as the Bird of the Year for 2025?
“Well, the main reason for choosing the grey wagtail was to draw public attention to its habitat. This bird is most often found near water—streams, rivers, and other waterways—and it depends on these habitats remaining in a natural or semi-natural state.
“It needs structured riverbanks that provide enough food—mostly insects and invertebrates—as well as suitable nesting spaces. That was the key motivation behind our decision.”
What are the main threats this small bird faces in its natural habitat?
“The usual suspects: river regulation, making streams and rivers too narrow, and reinforcing banks with concrete. When the banks have no vegetation or structural features like small hollows, the grey wagtail loses crucial nesting sites. That’s the biggest issue.
“Water quality can also be a factor, but as long as insects and invertebrates remain in and around the water, it’s not the primary concern. The physical structure of the banks—how the river or stream actually looks and functions—is far more important.”
The grey wagtail is not the first of its kind to be named Bird of the Year. In the past, you selected the white wagtail. Could you describe what the grey wagtail looks like and explain how we can distinguish the two species?
“The grey wagtail is slightly smaller than the white wagtail, but the main difference is its colour. While the white wagtail is primarily grey and black, the grey wagtail has a striking mix of grey and yellow, along with a black mask on its head. It’s actually more colourful and might catch people’s attention a bit more.
“That said, it can still be quite inconspicuous, and many people overlook it. Another key distinction is its song, though recognizing that requires a bit more expertise.”
As the name suggests, wagtails are known for their constant tail-wagging behaviour. Do we know the reason behind this unique trait?
“Well, there are several theories, though I’d call them more speculations or hypotheses.
“One idea is that wagging the tail signals to potential predators that the bird is alert. If a predator moves, the wagtail can spot it and escape. Personally, I have my doubts about this explanation.
“Another possibility is that the movement helps flush out insects, making them easier to catch. And yet another theory suggests it aids in flight manoeuvers, as the wagtail is a highly agile bird that can change direction very quickly.
“So while we don’t have a definitive answer, one thing is certain—it’s fascinating to watch any wagtail, whether grey or otherwise, and observe this behaviour.”
Finally, since you aim to raise public awareness of this species, what can people do to help protect the grey wagtail? Are there specific actions they can take to make a difference?
“Yes. People can be mindful when it comes to riverbank reconstruction. Nowadays, the public has a voice in these projects, so expressing concerns and advocating for nature-friendly designs can be very helpful.
“Additionally, people can directly support grey wagtails by installing nest boxes near rivers and streams. Small efforts like these can make a real difference.”
