line in a row

seen together during winter months

lined  up on ice in a row 

then leap up to the air all at once

when they decide it's time to go

 

ducks fly in a shifting v 

low in flight, not going far

I've got to stop right there. The title: Line in a row.  When you have a line, 

that's a row isn't it? I am sure that a line indicates a row. I don't have to say

straight  line. A line is a line, and that's a row. March is a month for poetry,

isn't it?  Keep your shoes on. Get in the box. 

get ready for opening day.

When the pitcher pitches,

knock it into the stands.

and when you round the bases

be sure to tip your hat to the fans.
