A CL65 flight crew returned to the departure airport after striking numerous birds shortly after takeoff.

Narrative

Departed Runway 36 in OMA. After being switched to departure control; we were given a heading of 090 and a climb to 15000 feet. In the turn; at approx. 3800 ft; we struck multiple birds. We immediately leveled at 4000 ft; and notified ATC that we would need to return to OMA; due to a bird strike. We noticed a significant change in the wind noise over the nose; and assuming there was significant damage; we declared an emergency with ATC. We were vectored back and cleared to land on Runway 32L. We completed all appropriate checklists; notified the cabin crew of what occured; with all pertinent information; and completed a visual approach and landing to Runway 32L; without further incident. Airport CFR responded; met us upon landing; and escorted us to the gate. No injuries were reported by any passengers or crew. Inspection of the aircraft exterior revealed substantial cosmetic and structural damage to the nose section of the aircraft. There was also evidence that birds had impacted both wings; as well as blood and feathers around both engine intakes. Maintenance was called; the flight was canceled; and the flight crew was released to rest.
