What kind of (ocean?) bird is this??
This could be an immature black-crowned night heron, Nycticorax nycticorax.
Lines of evidence:
- pale yellowish bill
- thick neck
- hunched back
- orange eyes
- head feather patterning consistent with "black crown" in adults

Immature Black-crowned Night Heron
Immature birds have a mix of juvenile and adult plumage. This individual has faint streaking on the chest, a dark gray cap, and a nearly complete dark gray back.

Adult Black-crowned Night Heron
Stocky and compact heron. Often tucks neck into its body creating a hunchbacked look. Adults have a black cap and back that contrasts with its whitish to pale gray belly and gray wings.

Note the fishing line tangled around the adult bird's feet. Must be a common trait!
