On 3 March 2009, after numerous complaints by players not hearing whenever the nests dropped to the ground, Jagex decided to upgrade the sound effect of a bird's nest, which is now a bird chirping. This is the same sound a Magpie makes. On 4 April 2011, with the release of Livid Farm, it was stated that the enhanced graphical trees around the clan camp would be 10% more likely to drop a bird's nest. This bonus does stack with a strung rabbit foot. The trees on Lunar Isle are no longer able to be chopped down, however.
