A wake of buzzards
A confusion of chiffchaffs
A chattering of choughs
A commotion of coots
A murder of crows
An asylum of cuckoos
A curfew of curlews
A trembling of finches
A swatting of flycatchers
A prayer of godwits
A crown of kingfishers
A parcel of linnets
A cast of merlins
A conspiracy of ravens
A worm of robins
A parliament of rooks
An exultation of skylarks
A murmuration of starlings
A hermitage of thrushes
A volery of wagtails
A museum of waxwings
A chime of wrens
An orchestra of avocets
A mural of buntings
A water dance of grebes
A booby of nuthatches
A quilt of eiders
A mischief of magpies
An aerie of eagles
A wisdom of owls
A quarrel of sparrows
A wisp of snipe
A kettle of swallows
An invisibleness of ptarmigans
A committee of terns
A descent of woodpeckers
A pitying of turtledoves
A banditry of titmice
A circlage of house martins
A scold of jays
A charm of goldfinches
A fall of woodcock
A deceit of lapwings

Maybe the earthworms came out for some air after the rain had stopped. There are more than fifty crows in this picture, and at least fifty more further down the street that I did not get into the frame.
