Amongst bird-keepers - seedeaters. Otherwise, there is no name that describes them all beyond the scientific name for seedeater - granivorous.
Considering that the name is "seed-eating", the birds eat seeds, not trees.

Birds may not be eating nyjer seed because they are not familiar with it or it may not be their preferred food. Additionally, some birds may have difficulty accessing the small seeds due to the size of their beaks.
I've never heard of a seed-eating bird... but if there is such a thing then yes, they would be a consumer.
Yes, seed-eating birds like finches and sparrows may adjust their feeding times to reduce competition for resources. Some species may feed early in the morning or late in the evening when other bird species are less active and thus reduce competition for food. Additionally, some birds may also feed opportunistically throughout the day to capitalize on available resources.

I have the same problem. It appears to me after observing them for a while, that they are actually feeding. I have poplar trees around my house and in the fall these trees produce little "helicopter things" that spiral to the ground. (Sorry I do not know what they are actually called). They fall into my gutters and the birds get them and peck the end that contains the seed. I assume they are eating this seed.
Could be for a variety of reasons, but grasping a tree bark or the seed itself could be some of them. Could be evolutionarily vestigial as well, like wings on ostriches.
Yes because they don't know how to hunt so if there was no more seed for them to eat then they would die because they don't know how to hunt

Sparrows are primarily seed-eating birds that are omnivorous, meaning they also consume insects and small invertebrates. Hawks are carnivorous birds of prey that mainly eat other animals, such as rodents and smaller birds, and are not considered omnivores.
