The population of ducks at Nabão River in Tomar
One of the attractions at Nabão River in Tomar, is the duck population. You can see dozens of this aquatic birds swimming, eating, playing and socializing in the peaceful surroundings of Mouchão Park and the river that crosses the City of Tomar. They especially like to gather in places where people feed them. People go to restaurants at lunch and dinner time and so do the ducks of Tomar. There are a couple of restaurants overlooking Nabão River that attract them there, because once people finish their meals, they feed them with food scraps, specially bread.

Nabão River in the City Tomar in Portugal, has a significant population of ducks who often approach restaurants near the river, to be fed by diners.

I couldn't possible identify these species of ducks at Nabão River in Tomar, because I don't know much about them, there are many types and they also tend to crossbreed, thus forming mixed flocks
