The baby swallow is a 4 candlestick bullish reversal pattern. The pattern starts with 2 consecutive black marubozu.

The third candlestick tells us that the bears are losing strength, and the final candlestick is an indication that the shorts are covering their positions.

Notice that on the forth day there is a significant gap up on the open and a new low on the close.
