I've never heard of a seed-eating bird... but if there is such a thing then yes, they would be a consumer.
Considering that the name is "seed-eating", the birds eat seeds, not trees.
worms
Primary consumer

A bird is a herbivore! * Some birds eat insects. I think birds are omnivores. So if the bird eats vegetation they are primary consumers if they eat animal food (insects, meat) they are secondary consumers.
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.
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.
Birds of prey, like Hawks are the main predators of Insect eating Birds. For example the Eurasian Sparrow hawk is the main predator of the Blue tit, Great tit, Wren, Eurasian Robin and Eurasian starling which are all Insect eating Birds.
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
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.
There are many examples, actually, all cases of a animal eating another animal are the examples of a consumer eating consumer in that all animals are consumer. for example, a sparrow eats a fly.
Amongst bird-keepers - seedeaters. Otherwise, there is no name that describes them all beyond the scientific name for seedeater - granivorous.
