Verdict

The call

The clearest difference is price: Bird Alone at Free against Ultimate Bird Simulator's $0.99. Bird Alone also leads on rating (4.8 vs 4.1) and update cadence (every 3 weeks vs every 81 months). Ultimate Bird Simulator's advantage is in-app purchases (none vs 3) and chart position (#74 vs unranked). On ads, device support and iOS requirement there is nothing between them.
