There's only a single event of someone reverse summoning prior to having a contract with an animal, so I wouldn't assume that everyone one has a "birth contract" with animal. Naruto [was reverse summoned by Gamakichi to Mount Myōboku](http://naruto.wikia.com/wiki/Reverse_Summoning_Technique). Reverse summoning is the same jutsu, except used by the animal of the contract, not the person.

I'm just curious did his snake summons not die after the fight with Deidara making it possible for him to make another contract?

<p>When Sasuke fights Danzo, on chapter 477 page 9, he uses summoning technique and a hawk appears.<br>
How and when did he sign a contract with hawks, and thanks to whom did he get it?</p>
