Baseline data of hematological values can be useful to compare with data of sampled Eurasian Griffons in the wild or received at rehabilitation centers. Preliminary hematological studies of the Eurasian Griffon were made in captive samples (625 Balash, J., S. Musquera, L. Palacios, M. Jiménez, and J. Palomeque (1976). Comparative hematology of some falconiforms. The Condor 78: 258–273. Close , 626 Ferrer, M., T. García-Rodríguez, J. C. Carrillo, and J. Castroviejo (1987). Hematocrit and blood chemistry values in captive raptors (Gyps fulvus, Buteo buteo, Milvus migrans, Aquila heliaca). Comparative Biochemistry and Physiology Part A, Comparative Physiology 87(4): 1123–1127. Close , 627 Polo, D. J., J. F. Celdran, V. I. Peinado, G. Viscor, and J. Palomeque (1992). Hematological values for four species of birds of prey. Condor 94(4): 1007–1013. Close ). In a sample of free living vultures (n = 54) from Cinctorres (Castellón Province, Comunidad Valenciana, Spain), mean hematological values were: WBC 10.45 K/μl ± 4.93 SD, RBC 2.41 M/μl ± 0.33 SD, HGB 15.35 g/dl ± 1.04 SD, HCT 49.33 % ± 4.28 SD, and MCV 207.37 fl ± 22.18 SD. In another sample (n = 18) from the same locality which were kept in captivity for 15 and 30 days, no significant differences in blood parameters were observed. In another sample (n = 51) kept in captivity for two years at Alcara Li Fusi - Rocche del Crasto (Sicily, Italy), a significant decrease in HTC, and an increase in HGB was detected (628 Giambelluca, S., M. Cammarata, S. Dara, T. Orefice, A. Camiña-Cardenal, and I. Vazzana (2017). The impact of captivity on some haematological parameters of Griffon Vultures (Gyps fulvus).

In nests (n = 18) from the islands Cres and Plavnik (Croatia), most insects (n = 249) present during the breeding season were beetles (64.26%) and ants (22.49%). Other groups of insects (cockroaches, web spinners, ants, flies, aphids) were found to occur occasionally in nests. Dermestid beetles were present in all nests, and the two most abundant species, Dermestes frischi and Anthrenus goliath, are necrophagous that feed on food remains (629 Dražina, T., and M. Špoljar (2009). Insect fauna in nests of the Eurasian Griffon Vulture (Gyps fulvus) in Croatia. Biologia 64(5): 969–973. Close ).

The featherwing beetle (Ptiliolum fuscum) (Coleoptera: Ptiliidae) was found in the plumage of the Eurasian Griffon, suggesting a phoretic interaction (630 Tomás, A., M. T. Rebelo, T. Valkenburg, and M. Darby (2018). An Association between the Featherwing Beetle Ptiliolum fuscum (Erichson) (Coleoptera: Ptiliidae) and the Eurasian Griffon Gyps fulvus (Hablizl) (Accipitriformes: Accipitridae) – First Report of a Phoretic Interaction between Beetles and Birds? The Coleopterists Bulletin 72(4): 662–664. Close ).

It has been established that there was an association between Neanderthals, raptors (including the Eurasian Griffon), and corvids, in which these species were hunted; on these hunted birds, evidence of markings, including cuts and scrapes, has been found on wing bones, which has been interpreted as evidence of the extraction of large flight feathers (631 Finlayson, C., K. Brown, R. Blasco, J. Rosell, J. J. Negro, G. R. Bortolotti, C. Finlayson, G. Finlayson, A. Sánchez Marco, F. Giles Pacheco, J. Rodríguez Vidal, J. S. Carrión, D. A. Fa, and J. M. Rodríguez Llanes (2012). Birds of a feather: Neanderthal exploitation of raptors and corvids. PLoS ONE 7(9): e45927. Close ). Radius bones of the Eurasian Griffon with a series of lined up holes were found at Hohle Fels (Basal Aurignacian, Upper Paleolithic, 40,000 years before present; Germany); these bones could have been used as musical instruments (632 Conard, N. J., M. Malina, and S. C. Münzel (2009). New flutes document the earliest musical tradition in southwestern Germany. Nature 460:737–740. Close ).
