We had to have part of the garden wall repaired recently, and part of the reason was because of the way all the mortar between the bricks had been pecked away. The sparrows had worked away at it over the years until the bricks were basically resting on top of each other with very little left holding them together. I found that by scattering a bit of rock salt on the pathway it seems to satisfy whatever mineral it is that they're after. Interestingly, it's only the sparrows that do this- I've not noticed any other of the garden birds either pecking at the brickwork or the salt.

I've certainly seen Feral Pigeons & Ring-necked Parakeets pecking at mortar.

I've just had to repoint some walls on the shed and dividing wall as the mortar was crumbling out, a weak mix or maybe lime mortar but never noticed the sparrows at it However we have a little polly grow house and most of the seedlings we were growing were suffering from slug and snail attack, so a liberal dossing of salt on the floor put down to discourage them, worked well. When I moved the grow house to point that bit of wall it left a hard rind of salt on the floor I just left it for the rain to dissolve. The sparrows had other ideas though especially the females and would come down for it even if I were sat just a couple of feet away. I did wonder at the time if some sort of mineral lick/block would be beneficial for the birds. ian

I've wondered about a mineral block or salt lick, too.
When I had horses we used to put a small one in their feed box in each stall- I'd thought about getting one of those to give it a try. My worry is it would just dissolve away in the first hard rain, but if I can work out a way to protect it in some way I might get one.

Birds such as sparrows etc need grit in order to grind their food in the gizzard, but birds such as hawks / falcons will take stones into their crop in order to clean the lining of the crop casting it out later the same as a pellet. Quite why birds eat salt isn’t clearly understood, in the case of your sparrows it could even be nothing more than curiosity, indeed, I’ve seen sparrows catching and eating butterflies before today.
Thinking about it I’ve seen butterflies feeding on dead animals and their faeces, presumable for the minerals it contains.
