Nacreous clam : Náyades

Imagen
We are all part of an ecosystem, and we think we know everything about life around us. But she takes different forms, it is often mysterious ...   The   nacreous clams of the hydric system of Rio de la Plata   are an example of this.  These clams are  native. They live in freshwater. They are large, and its outer surface is covered by a dark layer,   but they have a very beautiful inner nacre layer. They live in our ecosystem, buried in the sandy mud of unpolluted waterways, and part of their life cycle are parasites of   fishes .  In the early 50's they were used to make  buttons.  Today they are threatened by pollution, overfishing and the presence of invasive species that compete for their habitat.

Origin of the name Conchitas

T he names are lost in the swirl of time, and in a vast nearly untouched pampa ...  The name :  Shells appears in property  titles to the area near the stream since late 1700. Historians say  that the origin of the name is due to the abundance of shells in the area and also the exploitation of them for use as calcium oxide. But, today there is no trace of these shells, nor abandoned quarries where excavations were made​​.  However, there is an important fact to consider, in clean waterways of the Rio de la Plata are bivalves. These freshwater bivalves live buried in the mud and leave their shells to die. Perhaps there were  existed in other  time in this area, and giving rise to the name Shells.

The hummingbird song

These beautiful birds, the hummingbirds, are still visiting me. I like to observe them : their speed and grace. They become a flying rainbow. From time I watch them, I found a surprise : they sing. They like to do on top of an old  plum tree. They sing early  in the morning or at sunset. A man also heard a hummingbird singing and made a video. Todavía estos hermosos pájaros siguen visitándome. Me gusta observarlos : su velocidad, su gracia se convierten en arco iris voladores. De tanto observarlos me encontré con una sorpresa : cantan. Les gusta hacerlo en lo alto de viejo y seco ciruelo; por la mañana temprano o cuando se pone el sol. También escuchó su canto un señor  que pudo hacer el video.  ハチドリの歌  この綺麗な小鳥たちは、あれからずっと家の庭に訪れている、 私は観察が大好き、そのスピード、 彼らの魅力が空飛ぶ虹に変身する 長い間観察を続けていくと信じられないことが起こった ハチドリはさえずるのだ、 早朝や日の沈む時、枯れた梅の木に止まって歌っていた ある方が撮影したハチドリが歌っているビデオをここに紹介します
