Well done

The images look really good. As John said look out for the camera metering, if the subject is 33% or larger in the frame you. An use centre weighted metering but if it's smaller spot metering works better. Luckily OM-1 will give you a circle around the centre where you can judge how well the subject fits in the metering.
Centre metering gives you a good balance on exposure for the subject and a bit of the surrounding environment. With spot metering be careful th sacrifice you make for your environment because it will darken the exposure to the point that it may not be recoverable on a very bright subject (like the swans above), also called Low Key (where the image is predominantly black or shadows. If your subject is very dark (like a Blackbird, a Moorehen Duck or a Raven for example) the spot metering will overexpose any bright surroundings to bring the dark subject to a lighter shade, this is called High Key (where the image is mostly white or bright colours and only a very small portion of the image is darker).
The intention of metering so specifically is to preserve colour and details where you want them the most (for birds is feathers and features, like colour of the eyes or patterns on the feathers).
But be careful when you do decided to use spot metering because if you are in a very contrasting environment (shifting lights) and contrary subject (opposite values of light between the environment and the subject) you will have to sacrifice the environment for the subject and the difference between the shadows and the highlights is so great that 99% of the time the shadows or the highlights are not recoverable and you will have to stick with the original intent.
