Dutch authorities have seized 261 suspected wild parrot eggs at Amsterdam’s Schiphol airport ​after finding them in the hand ‌luggage of a couple flying from Central America to Asia, the Netherlands food and product safety watchdog ​said on Thursday.

Customs officers found the eggs ​on March 24, packed individually in paper ⁠and grouped in bundles wrapped in T‑shirts. ​When they examined one of the bundles, they ​heard chirping and discovered a parrot chick hatching. The bird was too young to determine its species, the ​Netherlands Food and Consumer Product Safety Authority (NVWA) ​said.

The Royal Military Police detained the two travellers, whose ‌identity ⁠and nationality were not made public.

All parrot species are protected under the CITES convention, a global treaty that regulates trade in endangered plants ​and animals, ​meaning strict ⁠rules apply to the possession and trade of the birds and ​their eggs. The travellers had no documents ​proving ⁠legal ownership, the NVWA said.

The eggs and the newly hatched chick have been transferred to ⁠a ​specialised care facility, where the ​remaining eggs will be incubated and the chicks cared for.
