In 2002 an automatic gateway was installed at the only access point to the Macaroni Penguin (Eudyptes chrysolophus) colony at Fairy Point, Bird Island. Taking advantage of the colony's geography, which ensured that the birds have only one route between the colony and the sea, the gateway initially recorded bird identities from implanted radio frequency identification transponders (RFID tags). In 2009 a weighbridge was installed which records the weight of each bird and the direction of travel and from 2011 onwards the two systems, RFID antenna and weighbridge, were built into the same unit meaning it was now possible to confidently match the crossing data with bird identities.

The bridge consists of two horizontal, rectangular, "marine plywood" panels set one above another and separated by two load cells, one at each end. When a penguin enters the bridge the system is triggered to record. The load cells are powered up and the force on both cells is measured 200 times a second for 3.7 seconds. The device records the sum of both load cells, this figure is used to calculate the penguin weight, and the value of the land side load cell, which is used to calculate direction of travel. The RFID antenna is also triggered to record. All records are time stamped. Further information on the set up of the weighbridge as well as the calculations used to establish bird weight can be found in Afanasyev et al. (2015). The weighbridge is calibrated and the data downloaded regularly: usually weekly at the height of the season. All data were collected under permit from the Government of South Georgia and the South Sandwich Islands. asNeeded completed
