Summer, which starts today in the northern hemisphere, is a season hightly appreciated by many people as days are longer, it´s mostly sunny and, alongside this, it's hot too. In fact, here in Spain the temperatures can be higher than 43ºC and it´s unbearable particularly for those who have to work outside. On the other hand, in the winter, in spite of the temperatures isn´t very pleasant either, has more detractors. This might have to do with the connection we usually have between winter season and feelings of sadness: days are shorter, it´s mostly cloudy and it´s enough cold as not to move away the fireplace . But to my mind, if I had to choose one season, I would choose the winter, mainly because it´s much easier to stand the cold, I think. And, what season do you prefer?

Yo prefiero el verano porque me gusta el calor.

The word calisthenics comes from the Greek words kallos (beauty) and sthenos (strength). It is a form of street workout which aims to build up strength and flexibility by doing gross motor movements such as pushing, pulling, lunging, and lifting using little or no equipment. I have been using this method, since I was at the university, to improve my general physical condition. It provides solid foundations for specific sports that I usually play, such as judo or running. This method is highly versatile because almost no equipment is needed. Therefore, you don't have to pay for a gym and you can exercise wherever you are, even in your hotel room if it's freezing outside. Furthermore, public street workout sites have been installed in public squares, parks, and big avenues around the world. Thanks for reading and correcting my entry.

Good job! I like the idea of public street workout sites. There aren't any yet where I live.

This happened on a typical day in my country. I was walking down through the neighborhood with my dog (a small sized brown hair 2 years old male datschund), on a summer night. It was all dark in the street and I was looking up to the trees. Suddenly, some leaves fall and I hear a sound like something was jumping and running through the branches. I stopped and looked around quietly for a while and I was totally shocked when I saw 5 RATS running between the trees!. The only thing that I did was run out of there. I never passed through that street again.

Good work! The errors in your writing were very minor.

Hi Andre, Good to hear from you, I am so excited to finally meet you and talk about our ongoing projects. In my opinion, you should not spend so much time collecting spectral data for all distribution of the lineages, considering that your study area is more restricted to Peru. I agree with you that examining the vouchers personally is important for a background. However, spectra data for few specimens by lineages should be plenty for comparing with your zone of introgression. Moreover, I also hope that the map that I sent you previously and which is part of my doctoral project should help you to have a overview of of the geographic variation in plumage color of this species even if it is only to compare with your transect. I have been studying color analysis since 2012 and I am sure the error measurement is very low for influencing the color analysis. For you to have an idea, database of bird plumage color measured with spectrophotometry of different researchers is available today collected with different protocols. For example, see: http://evoldir.tumblr.com/post/165392386711/other-birdcolourbase By the way, I would be happy to use your spectra data from Peru area and surely we can talk about colaborations in my paper later. Best regards
