After a cold Easter break in England, I returned to the warmer climes of Mexico yesterday and kicked off the new term's birding with an afternoon's walk around the reservoir at Parque 2000 in Queretaro.
I was surprised to see that large numbers of wintering wildfowl still remained on the lake. The usual cast of ducks were still there (Northern Shoveler, Blue-winged Teal, Mexican Duck, Ruddy Duck). It is possible that the Mexican Ducks (which occur here in larger numbers than most other places in Queretaro) will stay on to breed, as might a few pairs of Ruddy Ducks..
At the same time, some breeding activity was in evidence, most notably perhaps 8 pairs of Least Grebes going about their business (mating, collecting nest material etc). There also appeared to be a number of Black-necked Stilts sitting on nests. Hopefully, they will be successful in this disturbed, urban environment.
My most pleasing sighting of the afternoon was some migrating Northern Rough-winged Swallows mixed in with the hordes of Barn Swallows..
