It's Him...yes, learnt a lesson here! Luckily I managed to reserve one in Nottingham which wife is picking up later today as on a course there, lucky me 8)
True enough sir :D The photographer makes the photo
Your reading is correct: technique, rather than equipment is most likely to be the problem here. Spend £10 on a book (I recommend The KISS Guide to Photography (Keep it Simple Guides) https://www.amazon.co.uk/dp/1405301813/ref=cm_sw_r_cp_apa_i_pgT4Ab39N2PNK ) to upgrade your technique, rather than hundreds on equipment (which still won't help if your technique isn't right!)
If you're already invested in decent Canon lenses, you're probably better off upgrading your Canon body.
The zoom will depend on the lens you use. An 18-55 is fine for day-to-day use, but you'll probably want a long telephoto lens (i.e. at least 200mm) for bird photography. If you're serious about it, most of your money (by far!) will go on the lens rather than the body!
