False Bay cold and rainy black wingtips
The sea gull had more white than grey and black. Stood there for a minute then flew away.
I noticed bird tracks near water, specifically the Central Park reservoir in Manhattan. They appeared to be from a sea gull, as they were fairly large and I noticed many sea gulls in the vicinity. They were leading to the water and the area around it. The Central Park reservoir does freeze, but if it did during this winter it was only for a short period of time. Temperatures in this area fluctuate during winter due to the coastal location. It is possible it was frozen for some time earlier in the winter. This animal likely consumes more water in the winter as there are fewer water sources available and lower intense energy usage means less water is required.
The Common Gull (European and Asian subspecies; see below) or Mew Gull (North American subspecies) Larus canus is a medium-sized gull which breeds in northern Asia, northern Europe and northwestern North America. It migrates further south in winter. Its name does not indicate that it is an abundant species, but that during the winter it feeds on common land, short pasture used for grazing.
