A pair of nuthatches are in residence; I think this is the female.  

They are friendly and chatty; if the peanut feeder needs refreshing they will sit on deck chair and stare at me; they are acrobats ("creepers go up; nuthatches go down") and seem to be able to almost lay their head along their back when they look up and peer around while feeding (at least what seems to us) upside down. 

I don't really agree with the general opinion that they say "Ink Ink Ink" – but so far I cannot come up with an improvement on the interpretation.

A week or so ago a baby flew in the open deck door, made a U-turn into the kitchen where I was, and then tried to get back out through the closed window  to where its parent was sitting on the peanut feeder and screeching to it.  Other parent was in the nearby tree, also screeching.

Baby was not screeching and its fluttering against the window seemed more  "look at me!" than frantic.

A soft cloth got dropped gently over it, soothing words spoken, and as it got carried back outdoors it poked its head out of the cloth and looked around.  Parents were now both in the tree calling.

Once cloth was opened, it flew straight into the tree.  A minute or so later one of the parents was back on the feeder and soonest had chipped away some peanut which it flew back to the tree.  

A day ago one of the parents was on the feeder when I was out on deck having supper;  baby showed up and perched on a nearby chain.  Parent kept flying over to it and feeding it, talking to it.  Baby finally flew over to feeder.  Walked around.  Talked back in its more high-pitched voice.  Parent was pecking tiny pieces and feeding baby,  pecking larger pieces and feeding self.  Moving away from baby.  Baby followed.  Something seemed to click.  Baby gave a peck.  Got a piece of peanut.  Ate it.  Went back to following parent around.

Then a second baby showed up!  Parent busily fed both. Chorus of "Ink Ink Ink Ink….."

Parent flew back to tree.  Babies sat on feeder for a few seconds …. upright.  Then they flew away.

I went back to eating my supper.
