gape-mouthed

"You may be wise in your study in the morning,” (says brow-beating Johnson, to his gape-mouthed admirer Boswell,) “ and gay in company at a tavern in the evening.”

So in the spring my room and that portion of the veranda set aside for the purpose always had at least half a dozen cages and boxes containing gape-mouthed baby birds or birds that I had managed to rescue from the sportsmen and which were recuperating with makeshift splints on wings or legs.

A gape-mouthed wicker trunk served as a hive.
