 * Re: File:Sitta europaea -England -nest box-8.jpg. I found an image of a Nuthatch nesting in a nest box. It is any good for the article? Snowman (talk) 19:25, 4 April 2014 (UTC)
 * I think it needs cropping, but it go in the Breeding section instead of the intergrade  Jimfbleak -  talk to me?  16:37, 7 April 2014 (UTC)
 * I have cropped it and it is now shown in the article. Snowman (talk) 17:35, 7 April 2014 (UTC)
 * thanks for that and for referenced caption.  Jimfbleak -  talk to me?  07:15, 8 April 2014 (UTC)


 * Re: The FP File:Sitta europaea wildlife 3.jpg, which is the infobox image. It may be worth showing somewhere on the page, but not all FPs are suitable for the infobox image. I think that it would be better to show a more natural photograph in the infobox, perhaps of a Nuthatch climbing a tree trunk. Snowman (talk) 14:06, 7 April 2014 (UTC)
 * Swap with File:Sitta europaea wildlife 2 1.jpg ? I'll wait for you comments before I do these  Jimfbleak -  talk to me?  16:37, 7 April 2014 (UTC)
 * There a few photographs on Commons that would be fine for the infobox. A broad landscape image would be suitable, because of the proportions of the range map, so "File:Sitta europaea wildlife 2 1.jpg" may be too tall and narrow for the infobox. What about the previous infobox image? Snowman (talk) 17:35, 7 April 2014 (UTC)
 * Restored Kent bird to taxo, moved FP lower  Jimfbleak -  talk to me?  07:15, 8 April 2014 (UTC)


 * The three images of the S. e. caesia are all male, but I might be mistaken. I think that it would be beneficial to show a female. Is this a female nuthatch? File:Sitta europaea -Rouge Cloitre estate, Sonian Forest, near Brussels, Belgium-8.jpg.

About the article

 * Nuthatches eat nuts and sunflower seeds. I am surprised that they eat hazel nuts which are quite big and have a very hard shell, so I would be interested to know more about this. Some small and medium sized parrots have difficulty cracking whole hazel nuts. Do nuthatches swallow nuts and seeds whole like a pigeon or do the crack them open and eat the kernel like a parrot? Does the gizzard or stomach of the nuthatch have grinding capabilities? Snowman (talk) 17:54, 7 April 2014 (UTC)
 * What does hacking at nuts stuck in trees achieve? Does hacking imply pecking like a woodpecker? Do nuthatches crack nuts by hacking at them? Snowman (talk) 18:13, 7 April 2014 (UTC)
 * Is collecting nuts from the ground common? Would they eat nuts including beachmast that has fallen to the ground. Snowman (talk) 20:56, 7 April 2014 (UTC)


 * Despite it being the origin of the name, I managed to omit this because it was in the family section of my book, since all nuthatches do it. Basically, they wedge and smash. It's a different action to the parrots, relying on the pointed bill rather than strong jaws. I've added this. The feeding section says that they will feed on the ground, especially outside the breeding season. Beech mast is an obvious candidate, but I haven't found specific mention of it being taken from the ground despite having an article Nuthatch Sitta europaea Demography, Beech Mast, and Territoriality entirely about this food item  Jimfbleak  -  talk to me?  06:55, 8 April 2014 (UTC)


 * so that it is less likely that the nest will be taken over by Common Starlings&mdash;Snowman, I'm not happy about that. The Starling doesn't even occur in the north and east of the Nuthatch's range, and is unlikely to be a significant factor in the dense conifer forests of Russia. I've also referenced that Starlings do take over Nuthatch nests where both species occur (Nilsson). It may be a deterrent factor in the low density woodlands in western Europe, but it's a consequence rather than a reason.  Jimfbleak -  talk to me?  10:36, 8 April 2014 (UTC)
 * I note that you have already removed the text. I have had a look at the atlas again and I can confirm that it does say that about the birds of Great Britain and Ireland. I still think that the article would benefit from an explanation of why nesting birds could benefit from a nest build with mud to narrow the nest entrance. Snowman (talk) 11:15, 8 April 2014 (UTC)
 * I'm not doubting the reference, but in GB and Ireland much of the woodland is fragmented and accessible to open country birds like starlings. The nuthatch's preferred habitat is dense old woodlands that starlings do not use, and a good part of the distribution is out of the range of the starling even if fragmented woodland is present. As I said, it may be a consequence in limited parts of western Europe, but it can't possibly be the reason. I take your point about a reason being desirable, but there is no clear indication of what it might be. The obvious suggestions would be to exclude other hole nesters or predators, but the only larger hole-nesters in dense woodland are woodpeckers, which make their own nests. The plastering would be no defence against a Great Spotted or Black Woodpecker, which would just remove it or go through the wood, and weasels could just climb in. If you can rephrase as a consequence, perhaps following the Nilsson ref in Predators and parasites, which is on the same lines, I would have no problem with that  Jimfbleak -  talk to me?  12:31, 8 April 2014 (UTC)
 * I've had a rethink and restored your edit with some qualification. I've preceded it with a new ref which suggests that the primary function is to reduce predation.  Jimfbleak -  talk to me?  18:15, 8 April 2014 (UTC)
