\n\u2022 No fan cap mena de mala olor
\n\u2022 S\u00f3n un element b\u00e0sic per estudiar la dieta dels ocells i, alhora, quins micromam\u00edfers tenim en una determinada zona.
\n\u2022 Un sola egagr\u00f2pila pot contenir les restes de fins a sis preses.
\n\u2022 La seva dissecci\u00f3 \u00e9s fascinant i aporta gran quantitat d’informaci\u00f3.
\n\u2022 Hi podem trobar, per exemple, anelles o altres restes de marcatges cient\u00edfics.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
