Birds in the finch family do tend to descend on feeders in large numbers,
and their heavy bills make it easy for them to open seeds and eat them right
on the spot. So these birds then tend to sit at the feeder and eat, leaving
no room for other birds. (They also tend to leave a lot of shells and bird
droppings under the feeder.) In contrast, birds such as chickadees and
nuthatches don't travel in large numbers and eat by taking a single seed
away to a spot where they peck it open, which gives other birds a chance to
visit the feeder and also makes for less mess under the feeder.
Finches do tend to move on fairly quickly. As far as I know there
haven't been a lot of studies done on this, but the banding studies I am
aware of suggest that, unlike chickadees and nuthatches, finches do not tend
to stick around and keep visiting the same feeders over and over.
For those who want to continue to feed chickadees and nuthatches during
finch invasions, the types of feeders that do not have perches but instead
require birds to cling to something in order to get seed are sometimes
helpful. Feeders that only feed one bird at a time also tend to favour
chickadees and nuthatches.
There is one style in particular, a ball-shaped feeder often called a
"globe feeder" or "satellite" feeder, that requires the bird to hang from
the feeder port (there is no perch), that seems to lend itself to use by
chickadees and nuthatches as opposed to finches. Here's a picture of one
made by Duncraft:

(The ad copy says that it can be used by finches, but in my experience
finches have difficulty clinging to the port.)

We have had an invasion of pine grosbeaks since yesterday. Nice to see but
they hog the feeders and don't leave until they have taken every last seed.
