Didn‘t expect it so close to the city center near a small Creek.

Common kingfishers are important members of ecosystems and good indicators of freshwater community health. The highest densities of breeding birds are found in habitats with clear water, which permits optimal prey visibility, and trees or shrubs on the banks. These habitats have also the highest quality of water, so the presence of this bird confirms the standard of the water.[11] Measures to improve water flow can disrupt this habitat, and in particular, the replacement of natural banks by artificial confinement greatly reduces the populations of fish, amphibians and aquatic reptiles, and waterside birds are lost.[12] It can tolerate a certain degree of urbanisation, provided the water remains clean.[citation needed]

Wow, much brighter coloration than our belted kingfisher in Ohio.
