Default Is this position draw ?

8/8/B2k4/2p4R/3b4/4pK2/5p2/8 w - - 0 9

White : Kf3,Rh5,Ba6 / Black : Kd6, Bd4,c5,e3,f2

The only idea I have is trying to mate with the King and the Rook leaving
the black pawns where they are.

Thanks

I think White wins. White forces the Black king to the edge and
develops mating threats which Black can delay only by sacrificing the
pawns. The white king or rook are placed in a way that Black will lose
his pawns if he moves the bishop.

Example: 1. Ke4 Kc7 2. Rh6 Kd7 3. Kd5 Ke7 (3...Kc7 4. Rd6 Bc3 (4...Kc8
5. Kc6 Ka7 6. Rd8 plan Bb7 and Black can only sacrifice the pawns to
delay mate) 5. Rc6+) 4. Rd6 Kf7 5. Re6 Kg7 6. Ke4 Kf7 7. Kf5 Kg7 8.
Bc4 Kf7 9. Re4+ Kg7 (9...Kf8 10. Kg6) 10. Re7+ Kf8 (10...Kh6 10. Bd3
(threat 11. Kg4 Bg7 12. Re6+) and Black has to sacrifice the pawns)
11. Ke6 Bb2 12. Kd7 Bd4 13. Rf7+ Kg8 14. Ke8 Bc3 (14...Kh8 15. Kf8;
14...Bg7 15. Rf5+ Kh7 16. Kf7) 15. Re7+ Kh8 16. Kf7 Kh7 17. Re6 and
the threat Bd3+ and Re8+ can't be defended.

Probably the black defense isn't optimal, but it should be clear how
White proceeds.
