Silky the Crow


 * "You! you! Give us smooth!"
 * "Yes! you! Give us silky!"
 * — Silky the Crow

Silky the Crow is an invisible  NPC in Dark Souls II. They are similar to Snuggly the Crow  in Dark Souls, in the way that you can exchange particular items with them to receive other useful items.

They are located in Things Betwixt, on a ledge to the left when the player reaches the end of the path of the first tree, there is also a ladder that can be activated for a shortcut directly up to Silky's ledge.

Exchanges
In order to exchange items  with Silky, one must drop an item in the nest, and wait for a response. If they say "You, you. Not like that." "No, you, not at all." they won't accept it.

When a tradable item is dropped they will respond with "Yah,yah. So nice. So smooth." "Yah, yah. Silky smooth." and the trade will be complete.

Trivia

 * Silky speaks with two distinct voices, the first sounding male and the second sounding female, however they both talk in tandem and function as a single character.
 * She is never seen or spoken to directly, just like Sparkly the Crow in Demon's Souls and Snuggly the Crow in Dark Souls. They only speaks to theplayer.
 * There are no birds or eggs around Silky's location. Only an empty nest, which could imply that Silky isn't any sort of bird at all but instead is the nest itself.
