Narrative:
Was cleared on a visual to syr. When cleared the autoplt was on and was at 4000 ft MSL. At that time; I began a descent to 1800 ft to intercept the ILS course to runway 28. At the time of the descent; I noticed numerous towers on hills. I was flying in a valley between the 2 hills. At the time of noticing the towers; approach warned that we were getting closer to the towers. We were 300 ft (1800 ft AGL) above the towers and about 2000 ft horizontally. Factors that could have contributed to this were the reduced rest that the crew had the night before; and then flying an 8 hour day. I was tired during the flight from ZZZ1 to syr; dozing off a couple of times during the 40 min flight. This was the fourth flight of a 5-LEG day. After noticing the towers and being warned by ATC; I immediately stopped the descent and climbed 200 ft. Flight ended without incident.

Narrative: WAS CLRED ON A VISUAL TO SYR. WHEN CLRED THE AUTOPLT WAS ON AND WAS AT 4000 FT MSL. AT THAT TIME; I BEGAN A DSCNT TO 1800 FT TO INTERCEPT THE ILS COURSE TO RWY 28. AT THE TIME OF THE DSCNT; I NOTICED NUMEROUS TWRS ON HILLS. I WAS FLYING IN A VALLEY BTWN THE 2 HILLS. AT THE TIME OF NOTICING THE TWRS; APCH WARNED THAT WE WERE GETTING CLOSER TO THE TWRS. WE WERE 300 FT (1800 FT AGL) ABOVE THE TWRS AND ABOUT 2000 FT HORIZONTALLY. FACTORS THAT COULD HAVE CONTRIBUTED TO THIS WERE THE REDUCED REST THAT THE CREW HAD THE NIGHT BEFORE; AND THEN FLYING AN 8 HR DAY. I WAS TIRED DURING THE FLT FROM ZZZ1 TO SYR; DOZING OFF A COUPLE OF TIMES DURING THE 40 MIN FLT. THIS WAS THE FOURTH FLT OF A 5-LEG DAY.
