means Literally, seed mix for feeding birds; figuratively, a sum of money so trivial it's beneath serious notice.

from From 'bird' + 'seed' — the small, cheap grain scattered for pet or wild birds. Straightforward compound, no mystery there. The financial slang sense is the interesting leap: by the mid-20th century, American business and gambling talk had started using 'birdseed' for chump change — money fit only for pecking at, the way a sparrow pecks at scattered grain. The image does the work: real money is a meal, birdseed is just scraps.
