I see my woodpeckers eat quite a bit of suet this summer... it seems there's a lot of babies around my house. Could this happen to the woodies? C3D maybe you can answer?
My first impression is there is a Vitamin A deficiency but need to look up what's in the suet. I don't have time right now but will look into it later.
As with any diet for any species it is best to vary the foods so there is less of a chance to get a deficiency of this or that. We offer here a minimum of 6 kind of suet blends and more kind of seed and nut mixes than that. Plus the moistened dry dog food, fruits, berries and nectars. That way the birds are more likely to sample from the variety than stick with one type of food.
Thanks C3D for checking. I offer all sorts of different seeds, too (safflower, millet, regular and black oil sunflower, woodpecker nut mix - pistachio, peanut cashew, almond, etc, finch blend w/niger) plus suet (I like the no melt kind). I am glad to hear there is a good reason to.
The reason I believe it may be a Vit. a deficiency is that the BB foot looks like a possible ~bumblefoot~. Of course Vit. A deficiency is not the only cause of such a condition, that is to say, a corn / hyperkeratosis / swelling of the bottom of a foot but it certainly is near the top of the causes that may predispose birds to the condition and a secondary debilitating bacterial condition. They may also get a secondary yeast infection of the foot.
If a Vit. A deficiency is recognized fairly early, supplementation will result in resolution of the deficiency starting within a week. In reality this does not occur so rapidly as the secondary infections also need to be addressed and treated.
The primary sources for Vit. A are plant materials in deep green and orange veggies as well as egg yolk. Suet is high in protein, fat and the B vitamins. I do not know the specifics of the product mentioned in the article linked.
A Vit. A deficiency, or any nutritional deficiency, may occur in any species. A varied diet is the best diet to decrease the occurence of a nutritional deficiency.
Just as an aside ... for those who use suet ... If you take some suet product and grind it into the tree bark of the trunk and various branches ... you will increase the WP, Nuthatch, Creeper and other visitors! They **REALLY** like eating the suet this way and more are able to feed at a time if the food is spread around some.
I am NOT an avian specialist but just offer this observation as my ~best guess~ for the condition in question. It may or may not be the true problem.
