The Homing Pigeon candlestick pattern is formed by 2 candlesticks. The first is a long black candlestick. The 2nd is a smaller black candlestick whose real body is contained completely in the large black candlestick's real body. You'll notice this is very similar to the Bullish Harami Pattern except that the 2nd smaller body is white in that pattern, where here it is black.
