I sit in the top of the wood, my eyes closed.
Inaction, no falsifying dream
Between my hooked head and hooked feet:
Or in sleep rehearse perfect kills and eat.
The convenience of the high trees!
The air's buoyancy and the sun's ray
Are of advantage to me;
And the earth's face upward for my inspection.
My feet are locked upon the rough bark.
It took the whole of Creation
To produce my foot, my each feather:
The hawk is in control, and the earth is  personified  as looking up to the bird, awaiting its metaphorical ‘inspection’ or approval.  The hawk is clearly superior, able to analyse the way the world is seen as a whole, symbolising power and even  fascistic  control. The world, for its part, may fail to realise its own subservience.
