Nature / Landscape Artwork

Hello forum -

I have two pieces and was wondering if anyone was familiar with the artist. The larger piece with the mountains appears to be a watercolor while the other piece a serigraph. Initially I thought the artist was "Lohmann" however upon closer inspection, the first letter appears to be an upside down "T". Also, both signatures have what look like a bird next to them (I believe the bird is a cardinal).
