The effect of blood sampling on juvenile Buff-breasted Sandpipers (Tryngites subruficollis) was evaluated by comparing movements, mass, and survival of 10 broods (37 chicks) that were bled and eight broods (31 chicks) that were not bled. Blood was sampled from the jugular vein of chicks when they weighed 9.1 ± 0.9 g (x̄ ± SD) on or within 1 d of hatch. Chicks showed few short-term negative effects from blood sampling. Individual chicks suffered little physical injury, and five of eight chicks where injury occurred (i.e., hematomas formed) survived to fledging. Furthermore, bled broods gained mass at a comparable rate during the first 5 d post-hatch, and were resighted at similar frequencies as broods that were not bled. Bled broods moved slightly longer distances than control broods 1 d after hatch, however. This increased activity may have been stress-induced, but was only temporary; bled and control broods made similar long-term movements, and the probability of resighting was similar at fledging. With the proper precautions, it appears that Buff-breasted Sandpiper young can be safely sampled for blood at an early age without causing undue harm.
