figure out why this madness of an activity still takes

There are some blood samples taken from banded birds but on a small scale.

A few years ago I assisted the banding of shorebirds in the north west. The WA Agriculture & Health Departments wanted blood samples from the birds for the testing of diseases. This was arranged with the samples also being used for DNA testing as part of a world wide project. Blood samples were taken from up to 10 individuals of each species. The samples were only a very few millilitres (a small capillary tube). The bleeding was stopped, the wound dusted with an antiseptic powder, and the bird kept under observation until it was ready to leave (nearly all immediately the powder had been applied).

I seem to remember that about 200 samples from about 25 to 30 species were taken from a total of about 9,000 birds banded over the 10 weeks. All birds were released successfully. The banding records sent to the ABBBS were marked with a comment that blood samples had been taken.
