Abandoned to his fate. Out of ignorance, fashion or selfishness people buy pets which later are no longer possible to keep because they become too big or they requiere too much attention o they become naughty and so they lose the charm. It is very difficult to find a new home for them

Though this species was once recorded in 1998, Diego Bastías got the first photographic record and that is why we consider it a new species to the site.
The yellow-billed cuckoo reaches the south to spend the summer. It comes from the Northern Hemisphere, United States, where it breeds.

Azotacaballo/Luehea divaricata
2-3-19 © Sergio Piazza

It belongs to the family Tiliaceae. It is appropriate as an urban street tree. It loses its leaves in autumn and winter, which let the sun and light in and in the hot season its dense crown provides shade. It does not lift sidewalks.

It is more than 6 meters hight. Its leaves are simple and alternate. Flowers are rosy. Frutis open in 5 parts when ripe

It is called azotacaballo (horse whipper) in Spanish since flexible branches were used to beat the horse.  


The ponds

The two upper videos show the Gull Pond from one side to the other. The first one was taken from one window in the vegetation nearer Viamonte. The second one form the viewpoint which is some meters away from the Middle Path. One month to change the season the pond still keeps much water, unlike last year when it practically dried due to lack of rainfalls.

Taken from one of the main viewpoints we can see this pond with water too. A very benevolent summer favoured this situation.

This Oiketicus, unlike O. platensis and O. kyrbie, produces a long structure resembling a cigar without sticks. It is a silk cylinder where the caterpillar lives and lenghtens it as it grows. Females will stay in the nest since they are wingless. When they are ready to reproduce, males get to them. The females lay eggs and die. The larvae hatch and leave the bag to build their own.
