Fledgling Blackbird

I noticed this fledgling on our front lawn, having difficulty standing up & looking like it was calling when in fact it was gasping for for air as I realised when I went round to have look at it. It died in my hand a few seconds after I picked it up. Having a closer look I could see this hard ugly looking lump that spread from it`s throat & up around behind it`s eye, would it be Trichomonosis in such a young bird?
