Bird Courtshipping (Bio)

In Biology we've started learning about animal behaviours. One of the behaviours we are learning about is courtship behaviour. For this, I will be going over the King of Saxony's courtship behaviour as a bird of paradise. 

Courtship - is a behavioural feature in animals such as birds either dance, build or sing to attract a potential mate 

For these birds of paradise what females find attractive are their head feathers
So the longer the head feathers the more likely they are to find a mate and increase their reproductive success rate which in the end benefits them. These head feathers however have no other use other than being an ornament for attracting a mate. 

However, to even attract the attention of a female so she can get a good look at his head feathers, these males birds will perch themselves on a forest canopy in exploded leks and sing to attract the attention
of a female who could be a potential mate.  

Other than having these head feathers to find a mate, these feathers have no other benefits to these birds as they do not increase survival chances for the bird.

Potatools - Biology

In Biology were learning about human evolutions so how we started out as apes and involes into what we are now. The main thing we were learning out today was the tools that were made by our ancestors and how they were made and how they used them and what they were used for.

To learn about how they made the tools we decided to actually try making the tools like they would have back then, but instead of using rocks due to health and safety issues we used potatos and knives to shape our potatools. 

Below is a poster that was made showing our potatools and information about the potatools from that specific aera of time.
