Federal authorities at Miami International Airport intercepted 21 live birds hidden beneath the clothing of two travelers arriving on separate flights from Havana, Cuba, according to federal criminal complaints. The discoveries, made during inspections on Sunday and Tuesday, highlight an ongoing issue with the illegal smuggling of protected wildlife through South Florida ports of entry.
In the first incident on Sunday, 40-year-old legal permanent resident Alberto Hernandez Castillo arrived on a flight from Cuba and told Customs and Border Protection (CBP) officers that he had nothing to declare. According to court documents, an officer observed an unexplained bulge near the passenger’s waist and noted his nervous behavior, prompting a referral for secondary inspection.
During a pat-down in a secure area, officers discovered six cylindrical plastic containers wrapped in tape and black mesh hidden inside custom pockets sewn into Hernandez Castillo’s underwear. The containers held eight yellow-faced grassquits and two blue grosbeaks, which are protected under the Migratory Bird Treaty Act. Hernandez Castillo stated the animals were for personal use before invoking his right to remain silent. He was subsequently charged with smuggling goods into the United States and released on a $25,000 personal surety bond following a federal court appearance.
Second Incident Involves Eastern Air Express Flight
A second separate complaint revealed that federal agents intercepted another passenger carrying illicit wildlife just two days later. On Tuesday, Roberto Perez Quincosa arrived on an Eastern Air Express flight from Havana and likewise declared he had nothing to report to customs officials.
A physical search uncovered a specialized concealment garment containing taped plastic tubes equipped with breathing mesh. Agents extracted five Cuban bullfinches and six Cuban melodious finches, bringing the total number of intercepted animals across both flights to 21 live birds. Officials noted that neither passenger presented the mandatory documentation required to legally import wildlife into the United States.
Recurring Smuggling Patterns and Health Concerns
U.S. wildlife and customs enforcement agencies have documented multiple attempts to smuggle live birds into Florida from Cuba using similar concealment methods. In August 2025, a 22-year-old traveler was arrested at Miami International Airport with 40 live birds hidden on his body. A similar interception occurred in 2016 involving nine birds concealed in plastic tubes and a fanny pack.
Beyond legal violations involving protected species, federal health authorities warn that the unauthorized importation of wildlife poses serious biosecurity risks. Transporting birds without going through proper veterinary inspection and quarantine protocols creates a potential vector for the transmission of avian diseases, threatening both domestic animal populations and public health.
Legal Repercussions and Protections
What are the legal penalties for wildlife smuggling?
Individuals caught illegally importing wildlife into the United States face federal felony charges for smuggling goods, which can result in significant financial fines, probation, and federal prison sentences depending on the scale of the operation and the protected status of the animals.
Why are species like Cuban grassquits and bullfinches protected?
Many native and migratory bird species are shielded by federal legislation such as the Migratory Bird Treaty Act to curb illegal wildlife trafficking, prevent population decline, and preserve ecological balance across regional ecosystems.
What specific health risks do smuggled birds carry?
Unregulated animals bypass mandatory checks for infectious pathogens, raising concerns over the potential introduction of avian influenza and other transmissible diseases that can devastate local bird populations and agricultural industries.
