MORE BIRDS BACK - A Kingfisher showed up at the beaver pond...another Spring arrival. Ecologists talk about the concept of limiting factors: that the overall population of a species can be limited by just one scarce resource. In the case of Belted Kingfishers, that resource can be nesting sites. There are plenty of places with enough fish to feed family of Kingfishers, but for nesting they require the eroded face of a sandbank soft enough for the birds to burrow deep into it, and tall and steep enough to make it hard for predators to reach. We are SO pleased that the beaver pond has the right conditions for the Kingfishers.
