Birding photography is never cheap ! :devil:
If u r tight on budget, as u pointed out, 3rd party is ur best bet..
The TC will cause significant light falloff as it will cause ur aperture to drop to the same multiplier of TC u use (eg, u shoot at F4 X 1.7 TC = ~F6.8)
Its still ok if u shoot in sunny weather & light is enough but if in a gloomy weather then :sweat:
