So at work I'm using a neat map and data set (thanks @) that tries to identify promising areas for bird habitat conservation using a combination of our screening criteria such as wetland type, zoning, size, and biodiversity data (mostly bird sightings, because that's what is most available). This map identified an odd tiny green corner tucked way back into suburbia as an interesting spot. I knew there was a stream there and what looked like a little wetland but was curious to see for myself what had happened there. Ohhhhhhh i see........some very aggressive mallard, black ducks, domestics, hybrids, and all manner of angry waterfowl pecking at my boots.
On one hand it's kind of sad for the biologist in me to see huge quantities of non-native and domestic birds taking over this itty bitty patch of habitat, and to watch a set of weird behaviours caused by people feeding them. (And also lament the fact that I see fewer ducks out 'in the wild' doing their natural, wild, duckly things because so many will quickly learn to spend almost all their time in urban parks). But the more light-hearted (less bird snooty) side of me remembers that I'm an invasive species in this landscape too - and that the sight of hundreds and hundreds of cold hungry ducks determinedly waddling in from every direction DID kind of make my day. Plus seemingly no pigeons here (yet?!) so there's an extra star for that. .
