American Airlines said Flight 2163 took off at 10:08 a.m. and was en route to LaGuardia Airport in New York when it encountered the birds.

According to air traffic control recordings obtained by ABC News, the plane struck a flock of geese on takeoff. The pilot told air traffic control the engines were working but also said there was blood all over the windshield.

"When we landed, I looked at the pilot's window, (and) it was covered in blood and feathers," said passenger David Scott. "It was pretty dramatic."

Airline officials said the plane landed safely in Boston at 10:19 a.m. and taxied to the gate. Passengers boarded a replacement aircraft, which took off from Logan at 11:38 a.m. and landed in LaGuardia at 12:43 p.m.

"(Boarding) was actually much easier the second time around than the first time around," said passenger Frank Bagley. "It was great. I thought they handled it really (well). It was quick. I was not expecting that."

The flight had 99 passengers and four crew members, according to American Airlines.

American Airlines said its Boston maintenance team will evaluate the Embraer E190 aircraft, which is the company's standard procedure if one of its planes experiences a bird strike.
