Shore birds

[Phil C]

I found these vintage paintings of some type of shore birds. It appears these were done in the early 1900's. They are very intreasting, in it appears water colors, and real feathers were used to make the birds. Not knowing the type of shore birds that are hunted. I am not sure what type are trying to be presented, nor if the feathers are correct. I do not find any signature on the paints, but could be under the frame. Has any one seen birds done like this, can the birds be identified, and possibly anyone know if these were common?

Thanks Phil
