Not doing taxes is a plus for corvids in my book. Seriously, you picked one of the least impressive human activities. Makes me think about my potential reincarnation choices.
Crows fly, mate for life and are considered positive for the ecosystem. Humans do taxes.
Are you sure? I would be very surprised if a human could build a nest that a crow would accept unaltered.
Most birds’ nests are built much more intricately than just a pile of sticks thrown together! Usually built from layers of different materials, sometimes weaved or plastered with mud/clay/bird-spit.
E.g. sparrows pick up lavender in my garden, because the oils repel some pests etc.
