Corvid adaptability operates on cognitive rather than physiological dimensions. Crows in different cities develop location-specific behaviours within single generations: Japanese crows use pedestrian crossings as nutcrackers, while New Caledonian crows manufacture hooked tools unknown elsewhere. This cultural transmission enables adaptation speeds impossible through genetic evolution alone.

Urban crows have modified vocalisation frequencies to overcome traffic noise, altered nesting schedules to match human activity patterns, and developed techniques for exploiting fast-food waste specifically. They demonstrate what researchers term behavioural plasticity, the capacity to generate novel solutions to unprecedented problems rather than relying on inherited responses.

Corvid intelligence occupies a category that continues to astonish researchers. Crows demonstrate analogical reasoning, the ability to solve novel problems by applying principles learned in different contexts. They manufacture tools from materials not found in their natural environment, a behaviour once considered exclusively human. They plan for future events, cache food against anticipated shortages, and appear to comprehend cause-and-effect relationships with disturbing sophistication.

Perhaps most remarkably, crows recognise individual human faces and remember them for years. They communicate threat assessments to other crows, creating multi-generational grudges against specific humans who wronged them. A single act of unkindness toward a crow may result in harassment from that crow's descendants, a level of institutional memory most human organisations cannot achieve.

Crows manipulate humans through entirely different channels. Rather than exploiting emotional vulnerabilities, they employ transactional intelligence. Documented cases include crows bringing gifts to humans who feed them, apparently understanding exchange relationships. They remember beneficial humans across years, returning favours through pest removal, warning calls about dangers, and simple presence that many humans find meaningful.

This approach proves less reliable than feline emotional exploitation but demonstrates greater sophistication. Crows engage in what appears to be genuine reciprocity rather than one-directional manipulation. They assess individual humans independently, forming relationships with those who prove trustworthy whilst actively punishing those who betray them. The result resembles mutual respect rather than parasitism.

Crows hunt through intelligence rather than physical refinement. They drop shellfish onto rocks to crack them open, calculate traffic light timing to let cars crush walnuts for them, and coordinate group attacks on prey significantly larger than themselves. Their hunting success relies on problem-solving rather than physiological advantage, demonstrating remarkable adaptability across prey types and environments.

Opportunistic feeding extends their effective prey base to include items cats cannot access. Crows exploit human waste systems, raid unattended food sources, and even bait fish using bread as lures, a technique requiring foresight cats simply do not demonstrate. Their dietary flexibility ensures survival through conditions that would eliminate more specialised predators.

Corvid social organisation rivals primate complexity. Crows maintain extended family structures where offspring from previous years assist parents in raising new siblings. They hold apparent funeral gatherings around deceased members, behaviour suggesting awareness of mortality that raises uncomfortable philosophical questions. Pair bonds frequently last for life, with partners engaging in mutual preening, food sharing, and coordinated territorial defence.

Group decision-making occurs through observable democratic processes. Crows appear to debate travel routes, nesting locations, and responses to threats through vocalisation exchanges. Younger crows defer to elder expertise whilst maintaining the capacity for innovation. The resulting social flexibility enables rapid adaptation to changing urban conditions.
