Los loros sorprenden por su habilidad para imitar el habla humana, un fenómeno que intriga tanto a aficionados como a expertos. Un equipo internacional de científicos, liderado por la Universidad de Duke y citado por National Geographic, identificó la base cerebral que explica esta destreza y detalla cómo su estructura cerebral los diferencia de otras especies animales.

La comunicación animal abarca una gran variedad de sonidos —desde ladridos hasta cantos—, pero la reproducción espontánea de palabras y frases completas es extremadamente rara. Solo los humanos y muy pocas especies, como los loros, demuestran un dominio notable de la imitación del habla. Estas aves no solo copian sonidos, sino que pueden incorporar fragmentos completos de lenguas humanas a su repertorio.

El comportamiento espontáneo de los loros incluye la imitación de sonidos ambientales y vocalizaciones humanas. Como ejemplo, se observó periquitos Finsch en Costa Rica intercambiando “saludos” audibles. Este fenómeno captó la atención de la ciencia, que busca descifrar por qué estas aves muestran tanta afinidad por la imitación.

La investigación publicada en la revista Plos One y reseñada por National Geographic revela que la clave reside en características particulares del cerebro de los loros. A diferencia de pájaros cantores y colibríes, estas aves presentan una estructura denominada caparazón, exclusiva de su morfología cerebral.

La presencia del caparazón significa que los loros cuentan con áreas cerebrales adicionales que potencian la recogida y el procesamiento de información sonora. Esta estructura agrega complejidad, permitiendo un grado superior de reconocimiento, decodificación y reproducción de sonidos. Dichas diferencias, según el equipo de la Universidad de Duke, explican la capacidad única de estas aves para imitar tanto palabras como patrones melódicos complejos, algo que excede las habilidades de otras especies.

El caparazón es señalado como el centro que brinda a los loros una versatilidad sobresaliente en la imitación vocal, posicionándolos como los animales no humanos más hábiles para esta tarea.

Según científicos, la imitación en los loros no depende solo de áreas cerebrales especializadas. La interacción entre el sistema auditivo y el sistema motor resulta fundamental. Estas aves logran procesar los sonidos con gran precisión y los integran, mediante movimientos musculares y respiratorios muy coordinados.

Este mecanismo biológico convierte la información auditiva en acciones vocales concretas. La sintonía entre oído y músculo permite reproducir palabras, melodías y hasta sonidos ambientales con una fidelidad difícil de igualar. Así, la combinación entre un cerebro especializado y un sistema motor adaptado distingue a los loros entre el resto del reino animal.

Pese a la sofisticación interna, los expertos aclaran que no se hallaron adaptaciones anatómicas adicionales, como articulaciones u órganos vocales extra. No hay pruebas de que los loros cuenten con estructuras físicas distintas en su aparato vocal que expliquen su capacidad.

La singularidad de los loros radica exclusivamente en su estructura cerebral compleja y en la eficaz integración de sus sentidos. Su asombroso talento para la imitación del habla sigue siendo, por ahora, una consecuencia directa de su biología interna y no de mecanismos físicos ocultos.

Además, los estudios comparativos entre especies de loros revelan que el tamaño relativo del caparazón varía de acuerdo con la destreza imitativa de cada grupo. Especies conocidas por su gran capacidad para reproducir sonidos humanos, como el loro gris africano y el loro amazónico, presentan un caparazón más desarrollado que otros loros menos hábiles en la imitación. Este hallazgo sugiere una relación directa entre la extensión de esta estructura cerebral y el repertorio vocal disponible para cada ave, aportando nuevas pistas sobre la evolución de la comunicación compleja en el reino animal.

EXCLUSIVE: The Department of Homeland Security is calling on Virginia’s Democratic Gov. Abigail Spanberger to ensure local law enforcement cooperates with federal immigration officials by handing over an illegal immigrant with a lengthy criminal record who allegedly killed a woman earlier this week at a Virginia bus stop.

Police in Fairfax County, Virginia, arrested an illegal immigrant from Sierra Leone earlier this week on charges of second-degree murder after he allegedly fatally stabbed a woman, Stephanie Minter, 41, who was found dead at a local bus stop with several wounds to the upper body. 

The alleged suspect, Abdul Jalloh, 32, also has a criminal history of more than 30 arrests, according to DHS, including for rape, malicious wounding, assault, identity theft, contributing to the delinquency of a minor, assault and pick-pocketing.   

The request from the Trump administration comes after the newly elected Democratic governor of Virginia signed an executive order to end cooperation between federal immigration officials and state and local law enforcement, a move several Democratic Party governors have taken recently amid President Donald Trump’s move to increase deportation operations around the country. 

The DHS request asking Virginia officials to cooperate with ICE also comes after an illegal immigrant allegedly murdered someone just days after being released from jail for a separate crime in December.

«We are calling on Virginia Gov. Abigail Spanberger and Virginia’s sanctuary politicians to commit to not releasing this murderer and violent career criminal from their jail without notifying ICE,» said Deputy Assistant Secretary Lauren Bis. 

«This illegal alien’s murder of an innocent, beautiful American woman came less than 24 hours before Governor Spanberger’s demonization of ICE law enforcement. This heinous criminal is a perfect example of why we need cooperation from sanctuary jurisdictions and the importance of third country removals for the safety of the American people.»

Spanberger’s representatives did not respond to Fox News Digital’s request for comment. 

Jalloh entered the United States illegally in 2012, according to DHS, and immigration officials lodged an immigration detainer against him in 2020, whereupon he was granted a final order of removal by a judge who said he could be removed to any country other than Sierra Leone.

DHS indicated that ICE cooperation to ensure Jalloh’s deportation is evident after a case Fox News covered in December when a criminal illegal alien from El Salvador, Marvin Morales-Ortez, 23, allegedly killed a man just a day after Fairfax County jail officials let him go. 

The immigrant from El Salvador had been in custody on charges of malicious wounding and brandishing a gun, but police released him after the Fairfax County Commonwealth’s Attorney’s Office, led by George Soros-backed prosecutor Steve Descano, dropped the charges. 

Fox News Digital reached out to the Fairfax County Sheriff’s office to inquire about why the man had not been handed over to ICE. 

The sheriff’s office said, «ICE was aware of Morales-Ortez’s incarceration and elected not to seek a judicial warrant to ensure he remained in custody.

«The Fairfax County Sheriff’s Office follows all local, state and federal laws when determining whether a person is subject to release from the ADC,» the sheriff’s office told Fox News Digital at the time. «Immigration and Customs Enforcement (ICE) is automatically notified any time a person is booked into the ADC.»

The same sheriff’s office did not get back to Fox News Digital’s media inquiry for this story on DHS urging officials to cooperate with federal officials.

President Donald Trump on Friday said he was ordering every federal government agency to stop using Athropic AI immediately.

«THE UNITED STATES OF AMERICA WILL NEVER ALLOW A RADICAL LEFT, WOKE COMPANY TO DICTATE HOW OUR GREAT MILITARY FIGHTS AND WINS WARS! That decision belongs to YOUR COMMANDER-IN-CHIEF, and the tremendous leaders I appoint to run our Military,» Trump began in a lengthy Truth Social post Friday afternoon.

He added, «The Leftwing nut jobs at Anthropic have made a DISASTROUS MISTAKE trying to STRONG-ARM the Department of War, and force them to obey their Terms of Service instead of our Constitution. Their selfishness is putting AMERICAN LIVES at risk, our Troops in danger, and our National Security in JEOPARDY.»

The president said he would immediately direct every federal agency to stop using Anthropic technology.

«We don’t need it, we don’t want it, and will not do business with them again!» he continued.

There will be a six-month phase out period for agencies such as the Department of War, he added.

«Anthropic better get their act together, and be helpful during this phase out period, or I will use the Full Power of the Presidency to make them comply, with major civil and criminal consequences to follow,» he wrote.

He continued, «WE will decide the fate of our Country — NOT some out-of-control, Radical Left AI company run by people who have no idea what the real World is all about.»

Earlier this week, Anthropic CEO Dario Amodei refused demands from the Department of War to use its artificial intelligence for «all lawful purposes,» but Amodei said no, concerned over the possibility it could be used for «mass domestic surveillance» or «fully autonomous weapons.»

«The Department of War has stated they will only contract with AI companies who accede to ‘any lawful use’ and remove safeguards in the cases mentioned above. They have threatened to remove us from their systems if we maintain these safeguards; they have also threatened to designate us a ‘supply chain risk’ — a label reserved for US adversaries, never before applied to an American company — and to invoke the Defense Production Act to force the safeguards’ removal,» Amodei said in a Thursday statement.

He declared that the «threats do not change our position: we cannot in good conscience accede to their request.»

Assistant to the Secretary of War for Public Affairs Sean Parnell declared in a post on X that the department does not want to engage in either of those activities but is asking to use Anthropic’s AI for all legal purposes.

«The Department of War has no interest in using AI to conduct mass surveillance of Americans (which is illegal) nor do we want to use AI to develop autonomous weapons that operate without human involvement,» Parnell said in the post. «Here’s what we’re asking: Allow the Pentagon to use Anthropic’s model for all lawful purposes.»

«This is a simple, common-sense request that will prevent Anthropic from jeopardizing critical military operations and potentially putting our warfighters at risk. We will not let ANY company dictate the terms regarding how we make operational decisions. They have until 5:01 PM ET on Friday to decide. Otherwise, we will terminate our partnership with Anthropic and deem them a supply chain risk for DOW,» he noted.

Under Secretary of War for Research and Engineering Emil Michael accused Anthropic and Amodei of lying.

In a post on X, Michael called Amodei «a liar» who «has a God-complex.» 

«He wants nothing more than to try to personally control the US Military and is ok putting our nation’s safety at risk. The @DeptofWar will ALWAYS adhere to the law but not bend to whims of any one for-profit tech company,» he asserted.

In another post he asserted, «Anthropic is lying. The @DeptofWar doesn’t do mass surveillance as that is already illegal. What we are talking about is allowing our warfighters to use AI without having to call @DarioAmodei for permission to shoot down an enemy drone swarms that would kill Americans.»

«It is the Department’s prerogative to select contractors most aligned with their vision. But given the substantial value that Anthropic’s technology provides to our armed forces, we hope they reconsider,» Amodei said in a statement sent on Thursday to Fox News Digital. «Our strong preference is to continue to serve the Department and our warfighters — with our two requested safeguards in place. Should the Department choose to offboard Anthropic, we will work to enable a smooth transition to another provider, avoiding any disruption to ongoing military planning, operations, or other critical missions. Our models will be available on the expansive terms we have proposed for as long as required.»

«We remain ready to continue our work to support the national security of the United States,» he added.
