A consideration that is often overlooked is to ask the question of friends, associates and/or neighbors. If there is someone available, locally, who has a solution, that may be the best option, IME.
Let's say, for example, that the very best option happens to be a particular compressor, PCP and scope combination. The learning curve is going to be steep for someone not experienced with these types, and with shooting in general. A less perfect choice, that matches one's local support is often vastly superior, at least until you acquire sufficient experience to make critical assessments based on your own situation.
A huge consideration for someone new to shooting is trouble shooting issues, so a local support can make all of the difference.
I agree with Dstrac's suggestion, in that it is a .22 which IME is generally superior in terms of terminal energy with pellets. I agree that a PCP with magazine is usually a better solution, especially for one who is new to shooting. A wounded crow may recover enough to flap off, so the ability to follow up relatively quickly can be very useful. In addition, not having to change position to cock and load can be very useful.
I cannot comment on the Notos, although if it is a accurate and powerful as my old Gauntlet, crows are going to have a big problem.
IME, no matter what one chooses with regards the shooting sports, one will discover that "I should have" and can make improvements from there.
