<p>Olive ridley sea turtles (<i>Lepidochelys olivacea</i>) exhibit two nesting behaviors: solitary nesting and synchronized mass-nesting, known as <i>arribada</i>, with females able to switch between behaviors rather than being exclusive to one strategy. Although arribadas are thought to be driven by environmental and/or social cues that promote synchronized breeding, it remains unclear to what extent they can shape the spatial and temporal dynamics of nesting olive ridleys. Our study documents how nesting behavior influences the frequency of inter-beach movements and the length of within-season inter-nesting periods (IP). We examined records of 4,273 tagged and 555 recaptured individuals from 2016 to 2019 at Corozalito, a nascent arribada nesting beach on the Costa Rican Pacific, and its three neighboring solitary-nesting beaches. Inter-beach movements were recorded for 99 turtles (17.8%), primarily from solitary-nesting beaches towards Corozalito during arribadas. IPs of females nesting in arribadas were not consistent across seasons while IPs between consecutive solitary nesting events were stable across years and comparable to values reported for other olive ridley rookeries. We suggest that arribadas at Corozalito prompt inter-beach movements of olive ridleys that nest on solitary neighboring beaches, attracting them to the mass nesting location. Additionally, breeding synchrony may extend the IP of turtles that have already laid their first nest by delaying oviposition until the arribada begins. However, this delay appears to be context-dependent, likely influenced by the timing of arribadas and individual nesting histories. These findings contribute to better understanding the processes involved in the formation of arribadas and their associated nesting dynamics.</p>
