Another Kingbird chase

I went into Manhattan to see a reported Couch's Kingbird down in the west village section. I left the house at 9:05 and arrived at the intersection of 11th st and 4th st at 10:15, the most recent reported location. A couple of birders standing there told me the bird was there 5 minutes ago. I pulled the car over and the bird reappeared. I got decent looks. Later it was reported over at the intersection of Bank and Hudson st. I walked over there and got better looks. A crappy picture but good looks at a good bird

I wonder what makes a bird that normally resides in Texas show up in the middle of Manhattan. It's not like this is its migration path, I don't think they migrate this far north anywhere in the country, in checking the range in field guides they go no further north than southern Texas. There are occasional sightings along the east coast. Now here it is in the middle of winter in the middle of Manhattan, seemingly thriving. It looks like it is flycatching successfully. It has no problems hanging out on fire escapes and balconies of the apartment buildings. It has been seen in the small pocket parks in the area of the West Village. Maybe it's a beatnik. Maybe it likes jazz and the bohemian lifestyle. Just something to ponder.
