I went to a great place for hummingbirds observation, is located in my university and the entrance does not cost anything, so if there is anyone interested in seeing a huge variety of this small and fast birds, go there and give it a try. There are more than 60 types of hummingbirds, they are free but they stay there because they get fed every day, so there is no need to fly away looking for other places. I swear I saw more than 100 of them there.
These animals are the smallest birds in the world, some can weight up to 1,8 grams, and this might sound unbelievable but with this weight they and are able to fly 150 kilometers per hour, they have the fastest wing beats and their hearts beat up yo 1260 beats per minute. These little birds can burn 10 times as much oxygen per gram of body weight as does a human being. Because of all these amazing facts, they do need a lot of energy that take from the flowers.
As they are able to rotate each of their wings in circle, they are the only birds that can fly up, down, forward, backward, fly short distances upside-down and stay still in the air, to do so, they need to move their wings forward and backward in a repeated figure eight.
They are very smart; when it comes to protect themselves they can either flash or hide their bright colors when they need to; they can also remember every single flower they have been to, and they know how long it will take every flower to refill. These birds are very protective to what they consider their territory, which is their nectar sources, it can be certain area full of flowers or a feeder, they will aggressively defend it.
Hummingbirds can hear better than humans and see farther, they can also see the ultra-violet light.

Son muy inteligentes, pueden mostrar sus colores brillantes, y esconderlos dependiendo de la situación; pueden recordar cada una de las flores de las que se alimentaron, y saben cuánto tiempo se demora cada una de ellas en volver a llenarse de nectar. Son muy protectores con lo que ellos consideran su territorio, si se alimentan de un bebedero, lo van a defender agresivamente como si fuera suyo.
Los colibries no tienen sentido del olfato, pero pueden escuchar y ver mejor que los seres humanos, su vista llega a niveles más altos, y pueden incluso ver la luz ultravioleta.
